Non-excitation operable electromagnetic brake
Provided is a non-excitation operable electromagnetic brake that includes a manually operable rotary cam for switching over a rotor to a brake releasing state, but that allows easy recognition of switchover to the brake released state via an operation reaction force and that also allows reliable keeping of the rotary cam under its acting state. Even when an electromagnet is under a non-excited state, when a rotary cam is rotatably operated to an acting position, an acting portion of the rotary cam slidably operates a rotor via a releasing plate to a brake releasing state against springs. The acting portion of the rotary cam is formed linear along a tangent at a center of the acting portion with respect to a rotary cam rotational direction.
