Title:
CLUTCH MECHANISM AND DRAIN VALVE DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2018063001
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To properly operate a clutch switching member used also as a rotation restricting member.SOLUTION: A drain valve driving device 1 includes a first clutch mechanism 60 for connecting and disconnecting transmission of rotary torque to a transmission wheel train 50. The first clutch mechanism 60 includes a fan-shaped clutch switching lever 64 for pressing down the rotor pinion 51 to engage clutch claws with each other. The clutch switching lever 64 restricts rotation of the first rotor 522 in disengaging the clutches to have a load holding state. The clutch switching lever 64 is engaged with the first rotor 522 immediately after disengagement of the first clutch claw 61 and the second clutch claw 62 to restrict the rotation. Pressing force to rotate the clutch switching lever 64 is switched to pressing force from the rotor pinion 51 energized by a coil spring 63, from pressing force from a projection 55 of an output gear 54 before disengagement of the first clutch claw 61 and the second clutch claw 62.SELECTED DRAWING: Figure 17
