The ring 46 is housed in the ring groove 44 (see FIG. 2), and the pin 47 is housed in the pin hole 45. The pin 47 transmits a force in the axis O direction of the actuator 49 to the ring 46 via an annular plate member 48 arranged around the output shaft 12. When the actuator 49 moves the ring 46 toward the first member 20, the first engaging element 51 and the second engaging element 54 (see FIG. 6) come into contact with the ring 46 to reach the second hole 43 of the second member 40. You will not be able to engage. This cuts off the transmission of torque.

The third member 60 is an annular member for closing the first holes 25, 26 (see FIG. 4) formed in the first member 20 from the opposite side of the first surface 24. The third member 60 is arranged inside the protrusion 23 in the radial direction, and an oil hole 61 penetrating in the axis O direction is formed.

In this embodiment, the fastener 64 is a snap ring (for holes) (see FIG. 3).

FIG. 3 is an exploded three-dimensional view of a part of the clutch device 10, and FIG. 4 is a front view of the first member 20 in which the third member 60 is arranged. The first member 20 is coupled to the input shaft 11 (see FIG. 1) via a sleeve 55 that engages with a spline 22 formed on the inner circumference of the main body 21. The outer diameter of the sleeve 55 is smaller than the diameter of the inner peripheral surface 62 of the third member 60. A compression spring 50 and a first engaging element 51 are arranged in the first hole 25 of the first member 20, and a compression spring 50 and a second engaging element 54 (FIG. 6) are arranged in the first hole 26 of the first member 20. See) and are placed. In this embodiment, the compression spring 50 is a torsion coil spring. The first engaging element 51 includes a rectangular plate-shaped strut 52 and arms 53 protruding from the end of the strut 52 on both sides of the strut 52 in the width direction. The second engaging element 54 is the same component as the first engaging element 51 except that the orientation in the circumferential direction arranged on the first member 20 is different from that of the first engaging element 51, and includes a support column 52 and an arm 53. There is.

As shown in FIG. 4, in the first member 20, first holes 25 and 26 having different lengths in the circumferential direction of the first member 20 are alternately arranged in the circumferential direction. The first holes 25 and 26 have a substantially rectangular shape when viewed from the axis O direction. In the first holes 25 and 26, third surfaces 27 and 28 facing the axis O direction are formed on the entire circumference of the holes. The length of the first member 20 of the third surface 28 in the circumferential direction is longer than the length of the first member 20 of the third surface 27 in the circumferential direction. The first recess 29 is a recess that is connected to the first hole 25 and extends to both sides in the radial direction. The first recess 30 is a recess that is connected to the first hole 26 and extends to both sides in the radial direction.

The circumferential length of the first recess 30 is longer than the circumferential length of the first recess 29. The arm 53 of the first engaging element 51 (see FIG. 6) is arranged in the first recess 29, and the edge portion of the support column 52 of the first engaging element 51 is arranged in the third surface 27. Similarly, the second engaging element 54 (see FIG. 6) is arranged in the first recess 30 and the third surface 28. Since the circumferential length of the first hole 26 and the first recess 30 is longer than the circumferential length of the second engager 54, the second engager 54 is in the plane of the first recess 30 and the third surface 28. Can be slid.

In the first member 20, a second recess 31 connecting the first holes 25 and 26 in the circumferential direction is formed on the first surface 24. The second recess 31 is an annular recess into which the ring 46 arranged in the second member 40 (see FIG. 1) enters. The first member 20 is formed with a plurality of pin holes 32 penetrating in the axis O direction inside the second recess 31 in the radial direction. The pin hole 32 is a hole into which the pin 56 (see FIG. 3) is fitted. The pin 56 fits into the pin hole 63 penetrating the third member 60 together with the pin hole 32 of the first member 20, and regulates the relative rotation of the third member 60 with respect to the first member 20. The third member 60 is fixed to the first member 20 by matching the position of the oil hole 61 with the positions of the first holes 25 and 26. The size of the oil hole 61 is smaller than the size of the first holes 25 and 26.

5 (a) is a cross-sectional view of the first member 20 and the third member 60 in the Va-Va line of FIG. 4, and FIG. 5 (b) is a first view in which the second engager 54 and the compression spring 50 are arranged. It is sectional drawing of the member 20 and the third member 60. The second engaging element 54 is arranged between the second surface 42 of the second member 40 (see FIG. 1) and the third surface 28 of the first member 20. The compression spring 50 is arranged between the second engaging element 54 and the third member 60, and applies an elastic force to the portion of the support column 52 of the second engaging element 54 opposite to the arm 53 with the arm 53 as a fulcrum. Since the arm 53 is pressed by the second surface 42 of the second member 40, when the ring 46 retracts to the second member 40 side, the portion of the second engager 54 opposite to the arm 53 of the support column 52 is a compression spring 50. It rises to the side of the second member 40 by the spring force of. The same applies to the first engaging element 51 (see FIG. 6).

It will be described back to FIG. The first member 20 has a third recess 33 and a fourth recess 34 formed inside the second recess 31 in the radial direction. The third recess 33 is a recess in which a retainer 65 (see FIG. 6) that regulates the rise of the first engaging element 51 is arranged. The fourth recess 34 is a recess in which a compression spring (not shown) for urging the retainer 65 in the first direction (arrow F direction) is arranged. The retainer 65 moves in the circumferential direction through the third recess 33.

FIG. 6 is a front view of the first member 20 in which the first engaging element 51, the second engaging element 54, and the retainer 65 are arranged. The retainer 65 urged in the first direction (arrow F direction) by the elastic force of the compression spring (not shown) slides the second engager 54 in the first direction (arrow F direction), and at the same time, the first engagement. Covers a part of the joint 51. As a result, the retainer 65 prevents the first engager 51 from rising due to the elastic force of the compression spring 50 (see FIG. 3).

On the other hand, the second engaging element 54 can rise toward the second member 40 regardless of the position of the retainer 65. When the first member 20 rotates relative to the second member 40 in the first direction (arrow F direction) and the second engaging element 54 engages with the second hole 43 of the second member 40, the first member 20 and the second member 20 It rotates integrally with the second member 40 and transmits torque. Then, the retainer 65 is pushed by the second engaging element 54 and rotates in the second direction (counter-arrow F direction). As a result, the retainer 65 cannot cover the first engaging element 51, so that the first engaging element 51 can rise toward the second member 40 (see FIG. 1) by the elastic force of the compression spring 50 (see FIG. 3).

When the first member 20 rotates relative to the second member 40 in the second direction (counter-arrow F direction), the first engaging element 51 that rises to the second member 40 side causes the second hole 43 of the second member 40. Engage in. As a result, the torque of the first member 20 that rotates relative to the second member 40 in the second direction (counter-arrow F direction) can be transmitted to the second member 40.

In order to assemble the clutch device 10 including the two-way clutch, first, the first engaging element 51 is arranged on the third surface 27 of the first member 20, and the second engaging element 54 is arranged on the third surface 28. Next, the retainer 65 is arranged in the third recess 33 while the compression spring (not shown) is arranged in the fourth recess 34. Next, after inserting the ring 46 into the second recess 31, the second member 40 is arranged so that the second surface 42 abuts against the first surface 24 of the first member 20, and the ring groove 44 of the second member 40 is arranged. The ring 46 is housed in. Next, after inserting the compression spring 50 into the first holes 25 and 26 of the first member 20, the third member 60 is brought into contact with the first member 20, and the first engaging element 51 and the second engaging element 54 are brought into contact with each other. The compression spring 50 is sandwiched between the three members 60. Finally, the fastener 64 is fitted into the groove 36 to fix the third member 60. In this way, after the first engaging element 51 and the second engaging element 54 are arranged on the third surfaces 27 and 28, the compression spring 50 is arranged on the first holes 25 and 26, and then the first hole in the third member 60. It can block 25 and 26.

In the past, the third member was integrated with the first member (the first hole was a blind hole), so when assembling the clutch device, after arranging the compression spring 50 at the bottom of the blind hole, the first engagement When the coupling 51 and the second engaging element 54 are arranged, the first engaging element 51 and the second engaging element 54 are in a floating state by the elastic force of the compression spring 50. Since the retainer 65 and the ring 46 are arranged in such a state, the retainer 65 and the ring 46 also become a floating and unstable state. Therefore, there is a problem that the assembly workability is poor.

On the other hand, according to the present embodiment, since the first holes 25 and 26 penetrate the clutch device 10, the clutch device 10 is prevented from the unstable floating state of the first engaging element 51 and the second engaging element 54. Can be assembled. Therefore, the assembly workability of the clutch device 10 can be improved. Further, since the first holes 25 and 26 of the first member 20 penetrate the main body 21, the first holes 25 and 26 are easily formed in the first member 20 as compared with the case where the blind hole is provided in the first member. can.

The outer diameter of the sleeve 72 is smaller than the diameter of the inner peripheral surface 62 of the third member 60. A groove 73 extending in the circumferential direction is formed on the outer peripheral surface of the sleeve 72. With the third member 60 in close contact with the first member 71, the fastener 74 is fitted into the groove 73, and the fastener 74 is brought into contact with the third member 60 to bring the fastener 74 into contact with the third member 60 so that the third member 60 is relative to the first member 71. Is fixed. Since the protrusion 23 of the first member 20 (see FIG. 3) described in the first embodiment can be omitted, the weight of the first member 71 can be reduced.

Next, a third embodiment will be described with reference to FIGS. 9 and 10. In the third embodiment, a case where the first member 81 is divided into the first plate portion 82 and the second plate portion 86 will be described with the third surfaces 27 and 28 as boundaries. The same parts as those in the first embodiment are designated by the same reference numerals, and the following description will be omitted.

FIG. 9 is an exploded three-dimensional view of a part of the clutch device 80 according to the third embodiment, and FIG. 10 is a cross-sectional view including an axis O of the first member 81, the third member 60, and the fastener 64.

The first hole 83 and the first recess 29 regulate the position of the first engager 51 arranged on the third surface 27. The first hole 84 and the first recess 30 regulate the position of the second engager 54 arranged on the third surface 28.

The second plate portion 86 is formed with a plurality of rectangular hole portions 87 when viewed from the axis O direction. The hole portion 87 penetrates the second plate portion 86 in the axis O direction. The holes 87 are all the same size, and the size of the holes 87 is smaller than the sizes of the first holes 83 and 84. When the pin 56 is fitted into the pin hole 32 penetrating the first plate portion 82 and the second plate portion 86 and the first plate portion 82 and the second plate portion 86 are integrated, the hole portion 87 becomes the first. It is connected to the holes 83 and 84, and the third surfaces 27 and 28 are provided inside the first holes 83 and 84, respectively.

The second plate portion 86 is formed with first recesses 29, 30 and fourth recesses 34, which are connected to the first recesses 29, 30 and the fourth recess 34, respectively, formed in the first plate portion 82. A compression spring 50 is housed in the hole 87. A protrusion 23 is arranged on the outer periphery of the second plate portion 86.
