Claim Text:
1. An electric parking brake, wherein an electric motor is connected to a speed reduction mechanism through a linear motion mechanism, wherein a friction member mounted to the linear motion mechanism is configured to be pressed against a brake disk by rotating the electric motor, thereby generating a braking force, wherein with the braking force generated, an engaging member is configured to be moved to an engaged position where the engaging member is engaged in one of the linear motion mechanism and the speed reduction mechanism by a solenoid, wherein the electric parking brake comprises a monitor configured to detect a displacement of a plunger of the solenoid, and monitor a behavior of the engaging member based on the detected displacement, wherein the displacement is detected by detecting an inductance of the solenoid, and wherein a determination is made whether or not the engaging member has been moved to the engaged position based on the displacement of the plunger.
