Title:
INDUCTION RING AND DRAIN VALVE DRIVING DEVICE
Document Type and Number:
Japanese Patent JP2017155903
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve dimensional accuracy of a bearing portion formed on an induction ring.SOLUTION: A drain valve driving device 1 includes a second clutch mechanism 80 for switching a rotating torque transmission state and a non-transmission state of a transmission wheel train 50. The second clutch mechanism 80 includes a lock lever 83, a fan gear 82, a coil spring 86, a planetary gear mechanism 81, and an induction ring 46, and the rotation in a direction opposite to a rotating direction, of a rotor 45 is input to the induction ring 46 by operation of the planetary gear mechanism 81. The induction ring 46 has a metallic portion 461 composed of a non-magnetic metal and radially opposed to a magnet 451, and a resin portio 462 holding the metallic portion 461, and manufactured by insert-molding the metallic portion 461 to a resin. The resin portion 462 includes a bearing portion 466 slidably kept into contact with a shaft portion 452. The bearing portion 466 is disposed on a position radially overlapped to the metallic portion 461.SELECTED DRAWING: Figure 9
