Japanese Patent JP6863807
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor-operated valve 100 which can surely stop the rotation of a magnet rotor 202 by a stopper mechanism 1, and which makes the 1 strong.SOLUTION: A stopper mechanism 1 is constituted by a movable stopper 11, a lower end fixing stopper 12, a lower end side rotation stopper 13 and a compression torsion coil spring 14. The movable stopper 11 is energized to the lower end fixing stopper 12 side in an axial line L direction by the compression torsion coil spring 14. The lower end side rotation stopper 13 is provided at a magnet rotor 202. An engaging part 13c of the lower end side rotation stopper 13 and a triangular projection 11c of the movable stopper 11 are engaged with each other. A slide surface 11e of the movable stopper 11 is made to slide along a guide surface 12e of the lower end fixing stopper 12, the movable stopper 11 is made to displace in the direction coming closer to the engaging part 13c, and axial direction contact length of a contact surface between a surface 11d to be engaged and a main engagement surface 13d is prolonged.SELECTED DRAWING: Figure 4
