Title:
MOTOR WITH DECELERATION MECHANISM
Document Type and Number:
WIPO Patent Application WO/2022/270096
Kind Code:
A1
Abstract:
A cylindrical member 93 is provided with a pair of slits 93a, 93b extending in the axial direction of the cylindrical member 93. The opening widths of the pair of slits 93a, 93b in the circumferential direction of the cylindrical member 93 are narrower on the outside (opening widths W2, W4) of the cylindrical member 93 than on the inside (opening widths W1, W3) thereof. This makes it possible to prevent rainwater and the like from reaching a communication hole 91 inside the cylindrical member 93 and quickly discharge the rainwater and the like intruded into the inside of the cylindrical member 93 to the outside of the cylindrical member 93. Accordingly, it is possible to effectively prevent the rainwater and the like from intruding into the inside (hollow portion) of a gear cover 80, thereby enabling to improve a water exposure reliability.
