Abstract

To prevent the occurrence of noise due to step-out without upsizing a stepping motor by limiting a load. In a motor safety valve 1 for opening a valve port 13 by pulling up a valve element 6 by a stepping motor 2 in a state that a movable iron piece 5 is attracted by a movable electromagnet 3 mounted in a holder 31, a center part 62 abutting to the lower end of a rod 51 is surrounded by an annular deformation part 61. If the movable iron piece 5 is pressed down further when the valve element 6 is opened. The center part 62 moves toward a lower place to limit the load acting on the stepping motor 2.
