Title:
ROTATION REGULATION DEVICE AND DISCHARGE WATER VALVE DRIVE DEVICE
Document Type and Number:
Japanese Patent JP2018062999
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve workability during assembly of a torsion coil spring to be biased a rotation regulation member for regulating the rotation of a body of rotation.SOLUTION: In a discharge water valve drive device 1, a rotation regulation device 80A regulates the rotation of a lock gear 84 (the body of rotation) by rotating a sector gear 82 and a lock lever 83 based on the rotation of a rotor 45. The rotation regulation device 80A biases the sector gear 82 and the lock lever 83 in the return direction by a torsion coil spring 86 attached to a shaft portion 822 of the sector gear 82. The sector gear 82 includes a coil spring holding part 824 for holding the torsion coil spring 86 so as not to be dropped in the axial direction (a third direction Z). The coil spring holding part 824 has a structure in which the center part 825 of the shaft portion 822 is inserted into the center of a coil part 861; and an arm part 829 disposed on the outer peripheral side of the coil part 861 is engaged with a spring leg 862 so as to hold the coil spring.SELECTED DRAWING: Figure 11
