A connecting hole 34 is provided separately from the insertion hole 31. Accordingly, since it is not necessary to weld the connection terminals 46a and 46b and the brush 8 through the insertion hole 31, the size of the opening of the insertion hole 31 is necessary for assembling the control circuit member 25 into the gear housing 21. It becomes possible to make it the minimum size, and the design freedom of the gear housing 21 can be improved.

  (2) A mounting portion 33 for mounting and fixing the motor 1 is provided on the outer wall surface 21h of the circuit housing portion 21d. That is, since the circuit housing portion 21d is securely fixed, the vibration of the internal control circuit member 25 can be suppressed.

  (5) The connection hole 34 is formed so as to open in a direction parallel to the flat surfaces (flat surfaces 4a, 21e) of the gear housing 21. For this reason, the connection hole cover 35 that closes the connection hole 34 mainly protrudes in a direction parallel to the flat surfaces 4 a and 21 e, thereby contributing to flattening of the gear housing 21.

  (6) The plurality of connection terminals 46 a and 46 b of the control circuit member 25 are arranged in parallel along a direction perpendicular to the flat surfaces (flat surfaces 4 a and 21 e) of the gear housing 21. Thereby, since the opening direction of the connection hole 34 and the parallel direction of the plurality of connection terminals 46a and 46b are orthogonal, the connection terminal 46a and the brush 8 (internal connection terminal 12a) are easily connected from the connection hole 34. be able to.
