Title:
CLUTCH MECHANISM AND DRAIN VALVE DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2017155901
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To surely control rotation of a pinion provided with a clutch claw, in a clutch mechanism for connecting and disconnecting transmission of rotary torque from a rotor to a transmission wheel train.SOLUTION: A drain valve driving device 1 includes a first clutch mechanism 60 for connecting and disconnecting transmission of rotary torque from a motor 40 to a transmission wheel train 50. The first clutch mechanism 60 includes a first clutch claw 61 formed on a rotor pinion 51 disposed coaxially with a rotor 45, a fan-shaped clutch switch lever 64 for pressing down a second clutch claw 62 formed on a shaft portion 452 of the rotor 45 and a rotor pinion 51 in a -Z direction (clutch connecting direction), and a positioning mechanism 60A. The positioning mechanism 60A indirectly positions the rotor pinon 51 on a normal position 51A through a first rotor 522 engaged with the rotor pinion 51, and performing positioning in a rotating direction in assembling the rotor pinion 51 by engagement of a positioning recessed portion 68 and a positioning projection 69.SELECTED DRAWING: Figure 5
