Claims

[Scope of utility model registration request]

A housing having a one-way axial retaining portion on the inner circumferential surface, a fixed core coupled to one end of the housing, and when the fixed core is energized, it is attracted and prevents the rotation of the rotating body to be braked. a movable core having a one-way engaging portion facing opposite to the engaging portion in the axial direction on the outer circumferential surface thereof, and first and second engagers made of elastic bodies that engage with both the retaining portions, respectively; a combined pressing member;
and an elastic body that brakes the rotary body to be braked via the movable core when the fixed core is deenergized, and the first engagement element is elastically deformed and movable when the fixed core is deenergized. The iron core and the pressing member are allowed to move toward the braked rotating body, and the second engager is elastically deformed when the fixed iron core is energized and prevents the movable iron core from moving toward the fixed iron core. An electromagnetic brake device characterized in that it allows
