(See FIG. 2).

  As shown in FIG. 4A, a substrate mounting leg 44 (substrate mounting portion) is formed at the upper end in the longitudinal direction of the base portion 41 so as to protrude in a direction perpendicular to the axial direction of the rotary shaft 10. The board mounting legs 44 are respectively formed at both ends of the base portion 41 in the width direction (direction perpendicular to the paper surface in FIG. 4A). 4A and 4B, only one pair of the substrate mounting legs 44 is illustrated because they are arranged side by side in the width direction of the substrate support member 31 (the direction orthogonal to the paper surface). A fixing convex portion 45 for fixing the circuit board 32 is formed on one end face 44 a of the pair of board mounting legs 44. In addition, a support convex portion 46 that supports the lower end of the circuit board 32 is formed at the lower end in the longitudinal direction of the base portion 41.

  The circuit board 32 is supported by the board support member 31 in a state of being inclined with respect to the axial direction of the rotary shaft 10. More specifically, the circuit board 32 is inclined so that the upper end portion thereof (the end portion on the motor body 2 side) approaches the axis of the rotary shaft 10. As shown in FIG. 4D, an extension portion 32a extending from the center in the width direction is formed at the upper end portion (end portion on the motor body 2 side) of the circuit board 32, and the extension portion 32a. A Hall IC 33 as a rotation detecting element is mounted on the tip of the. That is, the circuit board 32 is supported in an inclined state so that the Hall IC 33 approaches the sensor magnet 10a. The extending portion 32a is configured to be in non-contact with the brush holder 7.

  The Hall IC 33 is opposed to the sensor magnet 10a in the radial direction, and the sensor magnet 10a and the Hall IC 33 constitute a rotation sensor for detecting rotation information (rotation direction, rotation speed, etc.) of the rotating shaft 10. doing. The Hall IC 33 detects a change in the magnetic field accompanying the rotation of the sensor magnet 10 a and outputs a detection signal to the control unit 34 mounted on the circuit board 32.

  The circuit board 32 is assembled in the direction perpendicular to the plate surface of the board 32 in a state of being inclined with respect to the board mounting leg 44 of the board support member 31. At the time of the assembly, the fixing projection 45 of the board mounting leg 44 is inserted into the fixing hole 32b formed in the circuit board 32, and then the circuit board 32 is heated by caulking the fixing projection 45. It is fixed to the tip of the mounting leg 44. The fixing hole 32b is formed so as to penetrate perpendicularly to the plate surface of the circuit board 32. 4 (a) and 4 (b) show a state before the heat-caulking of the fixed convex portion 45.

  Further, a fixing portion 47 connected to the lower end portion of the circuit board 32 by heat caulking is formed slightly above the support convex portion 46 in the substrate support member 31. The fixing portions 47 are formed at both ends in the width direction of the circuit board 32 (only one is shown in FIG. 4A).

  The front end surface 44 a of the board mounting leg 44 is an inclined surface corresponding to the inclination of the circuit board 32, and is in contact with the plate surface of the circuit board 32. The fixed convex portion 45 has a circular shape when viewed from the extending direction of the board mounting leg 44. The fixed convex portion 45 has the upper edge 45a (the edge on the Hall IC 33 side) assembled to the circuit board 32 when viewed from the width direction of the substrate support member 31 (the direction orthogonal to the paper surface in FIGS. 4A and 4B). The lower edge 45 b (the edge on the side opposite to the Hall IC) is parallel to the extending direction of the board mounting legs 44. Thereby, when the substrate support member 31 is molded, the fixed convex portion 45 is not caught by the molding die when the molding die is pulled out in the extending direction of the substrate mounting leg 44. That is, the fixed convex portion 45 is configured not to be undercut. Further, as described above, since the upper edge 45a of the fixed protrusion 45 is formed in a straight line parallel to the assembly direction of the circuit board 32, the fixed protrusion 45 is configured not to be undercut. However, the shape is suitable for the fixing hole 32b of the circuit board 32.

  A protruding portion 48 that protrudes toward the circuit board 32 is formed at the intermediate portion in the longitudinal direction of the base portion 41. The front end surface of the protrusion 48 is an inclined surface corresponding to the inclination of the circuit board 32, and is in contact with the circuit board 32.

  A control-side connection terminal 51 is provided between the board mounting leg 44 and the protrusion 48 in the base portion 41 in a state in which the control-side connection terminal 51 is partially insert-molded in the base portion 41. Note that a plurality of control side connection terminals 51 are arranged in parallel in the width direction of the substrate support member 31 (in FIGS. 4A and 4C, only the front side is shown). The distal end portion 51a of the control side connection terminal 51 protrudes from the base portion 41 to the circuit board 32 side, and the proximal end portion 51b protrudes to the opposite side. The base end portion 51b of the control side connection terminal 51 is joined to the internal connection terminal 14 by using, for example, Tig welding, and is electrically connected to each other. The distal end portion 51a of the control side connection terminal 51 is inserted into a terminal insertion hole 32c formed through the circuit board 32, and is electrically connected to the circuit board 32 by, for example, solder bonding.

  Here, as shown in FIG. 4C, the terminal insertion hole 32 c of the circuit board 32 is formed to penetrate perpendicularly to the plate surface of the circuit board 32, and is formed at the tip 51 a of the control side connection terminal 51. The inclined portion 51c is formed. The inclined portion 51c is formed on the upper surface (the surface facing the Hall IC side) of the tip end portion 51a of the control side connection terminal 51, and is set to an inclination angle corresponding to the inclination of the terminal insertion hole 32c (inclination of the circuit board 32). Yes. Thereby, when the circuit board 32 is assembled, the tip end portion 51a of the control side connection terminal 51 does not interfere with the terminal insertion hole 32c.

  Various electrical components are mounted on both surfaces of the circuit board 32. Among them, the electrical component 35 (relay or the like) mounted on the surface of the board support member 31 is inserted into the insertion portions 42 a and 42 b of the base portion 41. As a result, the substrate support member 31 and the circuit board 32 can be configured close to each other, and the control circuit member 25 can be downsized. In addition, while configuring the board support member 31 and the circuit board 32 close to each other, it is possible to extend the base portion 41 to the lower end portion (end portion on the cover 26 side) of the circuit board 32 and support the lower end portion thereof. As a result, the circuit board 32 can be stably supported.

  As shown in FIG. 3, the control circuit member 25 is arranged in the axial direction of the rotary shaft 10 from the opening 21 f into the gear housing 21 (circuit housing portion 21 d) in a state where the motor body 2 and the speed reduction portion 3 are assembled. Inserted. At this time, the press-fit portion 43 of the substrate support member 31 is press-fitted into the circuit housing portion 21d, and the control circuit member 25 is fixed. In this fixed state, the lower end portion of the control circuit member 25 projects outward from the opening 21f. Thus, since the control circuit member 25 can be assembled in the axial direction of the rotary shaft 10 that is the assembly direction of the motor main body 2 and the speed reduction unit 3, the assembly of the control circuit member 25 is facilitated. Since a special assembling facility for assembling the control circuit member 25 from other than the axial direction of the rotary shaft 10 becomes unnecessary, it contributes to cost reduction.

  In the fixed state of the control circuit member 25, the brush-side terminal 12 and the internal connection terminal 14 of the connector-side terminal 13 abut against the base end portions 51 b of the plurality of control-side connection terminals 51, respectively. And the internal connection terminal 14 come into contact with each other at a right angle (substantially in an L shape). And the base end part 51b of the control side connection terminal 51 and the internal connection terminal 14 are joined, for example using Tig welding as mentioned above, and are mutually connected electrically.

  After the terminal connection of the control circuit member 25, a metal cover 26 is caulked and fixed to the periphery of the opening 21f of the gear housing 21 (circuit housing portion 21d) so as to close the opening 21f. The cover 26 has a shape that bulges in correspondence with the protruding portion of the circuit member 25 so as to form a space that can accommodate a portion protruding outward from the opening 21 f of the control circuit member 25. The cover 26 not only closes the opening 21f, but also has a role of receiving heat generated from the control circuit member 25 and releasing the heat to the outside.

It is provided in a state of being inclined with respect to the axial direction of the rotating shaft 10 so as to approach the magnet 10a. For this reason, the circuit board 32 can be easily assembled to the circuit housing portion 21d while the Hall IC 33 mounted on the circuit board 32 is configured to face the sensor magnet 10a at a position close to the Hall IC 33.

  (2) In the present embodiment, the lower edge 45 b (the edge on the anti-Hall IC side) of the fixed protrusion 45 is the same as the extending direction of the board mounting legs 44 when viewed from the width direction of the board support member 31. In order to be parallel, when the molding die of the substrate support member 31 is pulled out in the extending direction of the substrate mounting leg 44, the fixed convex portion 45 can be configured not to be undercut. Further, since the upper edge 45a (the edge on the Hall IC 33 side) of the fixed protrusion 45 is parallel to the assembly direction of the circuit board 32, the fixed protrusion 45 is suitable for the fixing hole 32b of the circuit board 32. It becomes possible to make it a simple shape.

  (3) In the present embodiment, the board support member 31 is formed with insertion portions 42a and 42b through which the electrical component 35 mounted on the surface of the circuit board 32 on the board support member 31 side can be inserted. For this reason, it becomes possible to make the board | substrate support member 31 and the circuit board 32 close, and as a result, size reduction of the control circuit member 25 is attained. In addition, it is possible to suppress a reduction in the degree of freedom in layout of the portions (substrate mounting legs 44, support convex portions 46, fixing portions 47, and protruding portions 48) that support the circuit board 32 in the substrate support member 31, and as a result, It becomes possible to hold the circuit board 32 stably.

  (4) In the present embodiment, the tip end portion 51 a of the control side connection terminal 51 is formed with an inclined portion 51 c for avoiding interference with the terminal insertion hole 32 c when the circuit board 32 is assembled. As a result, the control-side connection terminal 51 can be provided perpendicular to the axial direction of the rotary shaft 10, so that the substrate support member 31 can be easily manufactured.
