Abstract
An electric braking apparatus is disclosed in which a rotational movement from a motor is converted into linear movement that moves a brake piston to generate braking force. The electric brake apparatus can perform full parking brake function without sacrificing its original braking function. In operation, immediately after generation of braking force caused by rotation of the rotor (26) supply of electricity to the motor is turned off. After supply of electricity is turned off, however, the rotor (26) is restricted from returning to its original position due to an engagement with an engaging claw (54) via a claw wheel (50), thereby keeping the barking brake remain effective. When electricity is thereafter supplied to the motor, the rotor (26) generates rotational torque sufficiently strong to push down the engaging claw (54) for disengagement, thereby releasing the parking brake.
