Abstract

An electromagnetic brake device presses a pressing plate against a brake rotor along an axis via a friction material by the electromagnetic force of an electromagnetic actuator. The electromagnetic brake device includes a support member that is disposed on the opposite side of the pressing plate to the brake rotor and that is supported by a housing so as to be displaceable along the axis and non-rotatable around the axis, and a shaft member that transmits a force in the direction along the axis between the pressing plate and the support member. An electromagnetic coil and an armature of the electromagnetic actuator are spaced apart from the pressing plate between the pressing plate and the support member, the electromagnetic coil is supported by the housing, and the armature is supported by the support member.
