  However, in the above conventional ignition switch device, since the rotor, the movable member, and the fixed member are arranged in a substantially straight line, the appearance of the cylinder body is vertically long (the axial dimension of the rotor is relatively long). There is a risk that the following problems may occur.

  For example, in a two-wheeled vehicle, the ignition switch device is normally disposed on the handlebar, but recently, it is disposed at various positions other than the handlebar (for example, a fuel tank in a large two-wheeled vehicle). Has also been proposed. Thus, as in the prior art, in a vertically long cylinder body, there are positions that cannot be disposed or positions that are difficult to dispose (for example, when disposed in a fuel tank, it is difficult to dispose in terms of layout or function). Therefore, it is necessary to reduce the longitudinal dimension of the cylinder body so that the cylinder body can be arranged or can be satisfactorily arranged at the place.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide an ignition switch device capable of setting a longitudinal dimension of a cylinder body to be small.

  According to the first aspect of the present invention, a rotor that is rotatably arranged in the cylinder body and has a key hole into which an ignition key is inserted, a rotor that can rotate in conjunction with the rotor, and a movable contact are formed. And a fixed member formed with a fixed contact that is fixed in the cylinder body and that can be contacted with or separated from the movable contact as the movable member rotates, and rotates the ignition key. In the ignition switch device that operates to start or stop the engine of a vehicle by bringing the movable contact and the fixed contact into contact with or apart from each other to turn on or off a predetermined electric circuit, the movable member is connected to the rotor. It is characterized by being disposed at a position overlapping in the axial direction.

  According to a second aspect of the present invention, in the ignition switch device according to the first aspect, the movable member is formed of an annular member having an insertion hole formed substantially at the center, and a rotating member interlocked with the rotor is provided in the insertion hole. It is characterized by being inserted and assembled.

  According to a third aspect of the present invention, in the ignition switch device according to the first or second aspect, the fixing member is fixed at a position overlapping with the rotor in the axial direction.

  According to a fourth aspect of the present invention, in the ignition switch device according to any one of the first to third aspects of the present invention, the vehicle is moved below the movable member and the fixed member in the cylinder body by rotating the ignition key. A lock mechanism for locking the handle is provided.

  According to the first aspect of the present invention, since the movable member is disposed at the position overlapping with the rotor in the axial direction, the movable member is disposed side by side with respect to the rotor (without overlapping). The longitudinal dimension of the cylinder body can be set smaller than that provided.

  According to the second aspect of the present invention, the movable member is composed of an annular member having an insertion hole formed substantially at the center, and is assembled by inserting a rotating member that interlocks with the rotor through the insertion hole. Can be stably linked to the rotor.

  According to the invention of claim 3, since the fixing member is fixed at a position overlapping with the rotor in the axial direction, the longitudinal dimension of the cylinder body can be set smaller.

  According to the fourth aspect of the present invention, the lock mechanism for locking the vehicle handle by the rotation operation of the ignition key is disposed below the movable member and the fixed member in the cylinder body. The rainwater or the like that has entered falls to the lock mechanism side, and it is possible to prevent the rainwater or the like from accumulating at the movable contact and the fixed contact of the movable member and the fixed member to cause an electrical failure.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The ignition switch device according to the present embodiment starts or stops a two-wheeled vehicle (vehicle) engine by rotating or rotating an ignition key to bring a movable contact and a fixed contact into contact with or away from each other to turn on or off a predetermined electric circuit. As shown in FIGS. 1 to 3, it is mainly composed of a cylinder body 1, a rotor 2, a movable member 3, a fixed member 4, a rotating member 8, and a lock mechanism 12. .

  The cylinder body 1 constitutes the casing of the ignition switch device, and the constituent elements (the rotor 2, the movable member 3, the fixed member 4, the rotating member 8, the lock mechanism 12, and the like) constituting the ignition switch device are included. The upper side is covered with a cover member 5. Further, the lock bar 10 of the lock mechanism 12 can be projected and retracted from the cylinder body 1.

  The rotor 2 is disposed in the cylinder body 1 so as to be rotatable around its axis, and is formed with a key hole 2a into which the ignition key IK is inserted. However, when the ignition key IK is inserted into the key hole 2a and rotated in a predetermined direction, the two-wheeled vehicle is operated by operating the lock mechanism 12 in the off position where the engine is stopped, the on position where the engine can be started. It can be rotated between the lock position for locking the handle bar included in the. In the present embodiment, if the engine is rotated clockwise from the off position (clockwise), the engine is turned on and the engine can be started, and leftward (counterclockwise) while being pressed from the off position. When it is rotated, the handlebar can be locked.

  A plurality of tumblers 2b (see FIG. 6) are arranged in the rotor 2 along the key holes 2a. When the ignition key IK is not inserted, the protruding state of the tumbler 2b is maintained and the cylinder body 1 The tumbler 2b is immersed in the rotor 2 and can be rotated when the ignition key IK is inserted into the key hole 2a.

  Further, the lower end of the rotor 2 is engaged with and connected to the rotating member 8, and a coil spring 13 is interposed between the rotating member 8 and the rotor 2. Thereby, the rotating member 8 can be rotated in a predetermined direction in accordance with the rotation operation of the rotor 2, and the rotor 2 can be pressed downward against the urging force of the coil spring 13. Note that a rotation operation from the off position to the lock position (a leftward rotation operation) is permitted by a pressing operation of the rotor 2 downward.

  In the present embodiment, a transponder T capable of wirelessly transmitting a predetermined ID code is embedded in the gripping portion (mascot portion) of the ignition key IK, and an antenna 6 (fixed to the substrate 7 in the cover member 5). This constitutes a so-called immobilizer. Here, the immobilizer is determined to collate the vehicle-specific ID code stored in the transponder T with the ID code stored in advance on the vehicle side, and the ID code from the transponder T is registered in advance. This means that the engine is allowed to start on the condition that

  That is, when the ignition key IK is inserted into the insertion hole 2a, the ID code transmitted from the transponder T is received by the antenna 6 and subjected to signal processing such as amplification processing by a predetermined circuit formed on the substrate 7. . Then, the signal-processed ID code is sent to, for example, a separately arranged immobilizer main body or an ECU (engine control device) provided in the vehicle, and it is determined whether or not it is a registered regular one. When the engine is authorized, the engine is allowed to start. When the engine is not authorized, the engine is not allowed to start even if the ignition key IK is rotated to the ON position.

  However, the cylinder body 1 is formed with a cylindrical portion B that rotatably accommodates the rotor 2, and a cover member 5 that accommodates the substrate 7 and the antenna 6 is disposed on the side of the cylindrical portion B. ing. The antenna 6 is disposed at a position on the side of the rotor 2 and below the insertion port P of the key portion IKb of the ignition key IK (see, for example, FIG. 2). In other words, in the past, the antenna 6 was disposed above the insertion port P of the rotor 2, whereas in the present embodiment, the coil is located near the insertion port P and below the insertion port P. A chip-like or chip-like antenna 6 is provided. Accordingly, the antenna 6 is disposed at a position overlapping the rotor 2 in the axial direction.

  The movable member 3 is rotatable in conjunction with the rotor 2 and has a movable contact 3a (see FIG. 9) formed at a predetermined position. More specifically, as shown in FIGS. 7 and 9, the movable member 3 is composed of an annular member having an insertion hole 3 b formed substantially at the center, and the rotating member 8 interlocked with the rotor 2 is connected to the insertion hole 3 b. It is inserted and assembled. In the present embodiment, the movable member 3 is formed with projecting portions 3c that project in three sides, each of the projecting portions 3c is formed with a movable contact 3a, and in the insertion hole 3b of the movable member 3. A convex portion 3d is formed on the inner peripheral wall, and the convex portion 3d is engaged with a concave portion formed in the rotating member 8 and locked in the rotational direction.

  Thus, when the ignition key IK is inserted into the key hole 2a and the rotor 2 is rotated from the off position to the on position, the rotation member 8 locked in the rotation direction with the tip of the rotor 2 also rotates in the same direction. Accordingly, the movable member 3 can be rotated around the axis of the rotor 2. The movable member 3 is provided with urging means including a spring and a ball (not shown) so that the urging means can press the fixed plate 9. The fixed plate 9 has a predetermined shape, and always urges the movable member 3 upward, and is given a moderation when the movable member 3 rotates.

  The fixed member 4 is fixed at a position facing the movable member 3 in the cylinder body 1, and as shown in FIG. 4, the fixed contact 4 a that can be brought into contact with or separated from the movable contact 3 a as the movable member 3 rotates. Is formed. As shown in the figure, the fixing member 4 is formed of an annular member having a through hole 4b formed substantially at the center, and the insertion portion 4b accommodates the cylindrical portion B of the cylinder body 1 (the rotor 2 is rotatably accommodated). To be inserted and fixed. In addition, the symbol h in the drawing indicates a wiring extending from the fixed contact 4 a of the fixed member 4.

  With this configuration, the movable contact 3a and the fixed contact 4a are brought into contact with each other by rotating the ignition key IK in a predetermined direction (rightward: clockwise) and rotating the rotating member 8 and the movable member 3 in the same direction. A predetermined electric circuit can be turned on to start the vehicle engine, and the ignition key IK is rotated in the direction opposite to the predetermined direction (leftward: counterclockwise) to rotate the rotating member 8 and the movable member in the same direction. By rotating 3, the movable contact 3a and the fixed contact 4a are separated from each other, a predetermined electric circuit is turned off, and the vehicle engine can be stopped.

  As shown in FIG. 8, the lock mechanism 12 is disposed further below the movable member 3 and the fixed member 4 in the cylinder body 1, and rotates the ignition key IK (specifically, to the left while performing a pressing operation). The steering wheel (handlebar) of the vehicle is locked by the rotation operation. The lock mechanism 12 includes a lock bar 10 and a cam member 11. The cam member 11 is connected to an extending portion 8 b that extends from the rotating member 8. Thus, if the ignition key IK is pressed and rotated leftward, the rotating member 8 rotates in the same direction, so that the lock bar 10 operates in the protruding direction via the cam member 11, and the tip side is It is inserted into a fitting hole formed in the handle bar and can be fitted and locked.

  Here, in the present embodiment, the movable member 3 is disposed at a position overlapping the rotor 2 in the axial direction (vertical direction in FIG. 2). In other words, the movable member 3 is disposed so as to be rotatable on the side of the rotor 2, and overlaps (is overlapped in the same direction) with respect to the axial direction of the rotor 2. As a result, the longitudinal dimension of the cylinder body 1 (vertical direction in FIG. 2) is at least the overlap dimension compared with the movable member 3 arranged below the rotor 2 (disposed without overlapping). (Dimension) can be set small.

  Further, as described above, the movable member 3 is composed of an annular member having the insertion hole 3b formed in the approximate center, and the rotation member 8 interlocked with the rotor 2 is inserted into the insertion hole 3b and assembled. The movable member 3 can be stably interlocked with the rotor 2. Furthermore, in this embodiment, since the cylindrical member B is inserted through the through hole 4b, the fixing member 4 is fixed at a position overlapping with the rotor 2 in the axial direction, like the movable member 3. Thus, the longitudinal dimension of the cylinder body 1 can be set smaller.

  Furthermore, a lock mechanism 12 that locks the handle (handlebar) of the vehicle by rotating the ignition key IK is disposed below the movable member 3 and the fixed member 4 in the cylinder body 1. Rainwater or the like entering from the key hole 2a or the like falls to the lock mechanism 12 side, and the rainwater or the like accumulates at the movable contact 3a and the fixed contact 4a of the movable member 3 and the fixed member 4 to cause an electrical failure. Can be suppressed.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, the movable member 3 is disposed at a position overlapping the rotor 2 in the axial direction, and the fixed member 4 is disposed on the rotor. It is good also as what was arrange | positioned in the position which does not overlap with 2 in the axial direction. Moreover, in this embodiment, although the immobilizer is arrange | positioned, you may apply to the thing where the said immobilizer is not arrange | positioned, or the thing which replaced with the immobilizer, and other crime prevention mechanisms were arrange | positioned.

  Further, in the present embodiment, the lock mechanism 12 including the lock bar 10 and the cam member 11 is disposed. However, the lock mechanism 12 that does not include the lock mechanism 12 or other forms that can lock the handle bar. The present invention may be applied to a device provided with the lock mechanism. In addition, in this embodiment, although applied to a two-wheeled vehicle, you may apply to the ignition switch apparatus of other vehicles (construction machines, such as a motor vehicle and a shovel car, or ATV).
