- the gear housing 8 is provided with one convex portion 27 having a screw hole 27 a at a position corresponding to the center of the plate portion 13, and the control circuit board 51 has the convex portion 27.
- a through hole 65 is formed at a position corresponding to the portion 27.
- the plate portion 13 is tightened and fixed to the gear housing 8 by screws 23 and nuts 24 at a total of five locations including the four corners and the central portion.
- a concave portion that fits with the convex portion 27 is formed so that the screw 23 does not come into contact with the upper portion 13. I have. Therefore, by clamping a rectangular metal plate 66 having a pair of screw holes between the head of the screw 23 and the end of the plate 13, the tightening force of the screw 23 is reduced. The end of the plate 13 is transmitted to the end. Also, a pair of screw holes 27 a on the side close to the worm wheel 7 is formed in one convex portion 67. I have.
- the control circuit board 51 is accommodated in the accommodating portion 52 provided in the gear housing 8 in a state orthogonal to the axial direction of the motor portion 2, and the connector case 53 is adjacent to the motor portion 2. Are located in Therefore, since it is not necessary to form the connector case 53 in the gear housing 8, the size of the gear housing 8 can be reduced. In addition, the gear housing of the normal type motor and the gear housing of the smart type motor can be shared, and the manufacturing cost of the motor can be reduced.
- the gear housing 8 is formed with a positioning projection 61 having a fitting concave portion 62, and the plate portion 13 is formed with a positioning projection 63. Therefore, when assembling the brush holder 10 to the gear housing 8, the brush holder 10 can be positioned with respect to the gear housing 8.
- the seal member 21 covering the plate portion 13 is not limited to an elastomer, and may be, for example, rubber. Further, the seal member 21 may be made of a viscous material, for example, butyl rubber.
- the seal member 21 may cover only the surface of the plate portion 13 facing the gear housing 8.
- the sinole member 21 is not limited to a configuration integrally formed with the plate portion 13.
- a seal The member 21 may be a rubber packing separate from the plate portion 13.
- the brush holder 10 and the case 15 may be formed integrally.
- the number of parts can be reduced as compared with the case where the brush holder 10 and the case 15 are separate bodies, and the cost can be further reduced.
- FIG. 5 (a) shows an example in which the brush holder 10 and the case 15 are integrally formed.
- the control circuit board 14 may be supported on the gear housing 8 by screwing.
- the control circuit board 14 has a screw hole 14 a formed at the base of the board body 35.
- a pair of screw holes 14a is formed, and mounting pieces 71 protruding in the axial direction are formed at positions corresponding to the screw holes 14a on the end face 8a, and each mounting piece 7 1
- Each has a screw hole 72 formed therein.
- the control circuit board 14 since the control circuit board 14 is not inserted into the slit 32, the control circuit board 14 as a whole protrudes from the gear housing 8 more than the case where it is inserted into the slit 32, and the female terminals 3 9 Also protrude further from the gear housing 8.
- the connection terminal 22 connected to the female terminal 39 is disposed in the case 15. Since the mounting piece 71 protrudes from the gear housing 8, it can be easily formed when the gear housing 8 is formed by the mold, but the slit 32 is difficult to be formed by the mold. Therefore, in this configuration, the gear housing 8 is easier to manufacture than when the slit 32 is formed in the gear housing 8.
- the case 15 and the gear housing 8 may be positioned in the radial direction of the motor unit 2 by fitting using a relationship of unevenness.
- the gear housing 8 includes a convex portion 27 at a central portion with respect to a longitudinal direction of the end surface portion 8 a and a convex portion 27 far from the worm shaft 6.
- a pair of fitting projections 74 are formed.
- a fitting recess 75 is formed in the flange 45 at a position corresponding to the fitting projection 74.
- the fitting convex portion 74 and the fitting concave portion 75 are fitted to each other so that the diameter of the motor portion 2 is reduced.
- the case 15 can be easily positioned with respect to the gear housing 8 in the different directions.
- the connector case 53 may be formed separately from the plate portion 13. For example, a through hole 16 is formed in the plate portion 13, a flange portion 45 is formed in the connector case 53, and the connector case 53 is passed through the through hole 16, and the flange portion 4 is formed.
- the connector case 53 may be assembled by sandwiching 5 between the gear housing 8 and the plate portion 13.
- a fitting recess may be formed in the positioning protrusion 63 of the brush holder 10, and the positioning protrusion 61 of the gear housing 8 may be formed in the fitting recess. Good.
- the positioning projections 61 and 63 need not be provided.
- the control circuit board 51 may be assembled to the gear housing 8 by heat staking, engaging with claws, or the like.
- the accommodating portion for accommodating the control circuit board 51 may not be provided in the gear housing 8 but may be provided in the plate portion 13.
- the gear housing 8 does not have to be configured to support the control circuit board by claw-screw tightening or the like.
- the control circuit board may be held by screwing the yoke 5 and the gear housing 8 together.
- the gear housing 8 and the control circuit board may be fixed by heat caulking.
- connection terminals 22 may be provided on the control circuit boards 14 and 51, and the female terminals 39 may be provided on the brush holder 10.
- the position of the screw 23 and the nut 24 is not limited to the configuration in which the screw 23 is inserted from the motor unit 2 side and fastened to the nut 24, and the positional relationship between the screw 23 and the nut 24 may be reversed. Further, the screw 23 may be directly screwed into the gear housing 8. What tightens the yoke 5 and the gear housing 8 is not limited to the screw 23, but may be another tightening member.
- the clutch 4a may be omitted, and the armature 4 and the worm shaft 6 may be directly connected.
- the motor 1 is not limited to the drive source of the vehicle power window device, but drives other devices.
- the power source may be used.
- a motor section a reduction section for reducing the rotation of the motor section, a control circuit board including a connector body, a board housing section, and a gear housing between the motor of the motor section and the gear housing of the reduction section.
