Patent ID: 7279817

Claim:
A motor comprising: a motor arrangement; a speed reducing arrangement that includes: a speed reducing mechanism that decelerates rotation of the motor arrangement; and a speed reducing mechanism receiving portion that receives the speed reducing mechanism; a control circuit board that is received in the speed reducing mechanism receiving portion, wherein at least motor-side terminals for supplying electric power to the motor arrangement are mounted on the control circuit board as electrical circuit components; and a connector housing, to which an external connector for connecting with the motor-side terminals is fitted, wherein: the connector housing is formed separately from the speed reducing mechanism receiving portion; the connector housing at least includes: a connector supporting member that supports the external connector relative to the speed reducing mechanism receiving portion; and an installation opening sealing member that is elastically deformable; the installation opening sealing member is interposed between the connector supporting member and an outer surface of the speed reducing mechanism receiving portion and is secured to a connector installation opening, which is formed in the speed reducing mechanism receiving portion; the connector supporting member is formed into a tubular body and includes an annular flange portion, which protrudes outward from an outer peripheral surface of the connector supporting member; and the installation opening sealing member is interposed between the flange portion and the outer surface of the speed reducing mechanism receiving portion, which is located around the connector installation opening.
