Title:
CLUTCH MECHANISM AND DRAIN VALVE DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2018063000
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent axial movement of a rotor including an engagement portion for positioning a rotor pinion, by the rotor pinion.SOLUTION: In a drain valve driving device 1, a rotor pinion 51 is assembled so that clutch claws are not interfered with each other by engaging a positioning projection 69 disposed on a first rotor 522 of a planetary gear mechanism 52 with a positioning recessed portion 68 disposed on the rotor pinion 51. The first rotor 522 includes a relief portion 692 disposed on an angular position different from the positioning projection 69. The rotor pinion 51 is movable in an axial direction (third direction Z) through the relief portion 692. Accordingly, by rotating the first rotor 522 to make the relief portion 692 face a side of the rotor pinion 51, after assembling the rotor pinion 51, the first rotor 522 is prevented from being pressed up in a +Z direction with the rotor pinion 51.SELECTED DRAWING: Figure 8
