Title:
ROTATION REGULATION APPARATUS AND DRAIN VALVE DRIVING APPARATUS
Document Type and Number:
Japanese Patent JP2017158391
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To increase magnetic induction force generated between a magnet and an induction ring so as to increase holding force to hold a rotation regulation member.SOLUTION: A drain valve driving apparatus 1 comprises a second clutch mechanism 80 to switch status in which a transmission ring column 50 transmits/does not transmit rotation torque. The second clutch mechanism 80 includes a rotation regulation apparatus 80A to regulate rotation of a lock gear 84. The rotation regulation apparatus 80A has a lock lever 83, a fan gear 82, a coil spring 86, a planetary gear mechanism 81, and an induction ring 46. The induction ring 46 is input with a rotation direction and a reverse direction of the rotor 45 by operating the planetary gear mechanism 81, to increase relative rotational speed between a magnet 451 provided on the rotor 45 and the induction ring 46. Accordingly, magnetic induction force generated between the induction ring 46 and the magnet 451 is amplified and holding force to hold the lock lever 83 is increased.SELECTED DRAWING: Figure 9
