ACTUATOR FOR ELECTRROMECHANICAL BRAKING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an actuator for an electromechanical braking device including a piezoelectric assembly particularly simple in electric connection to a piezoelectric element.

SOLUTION: The actuator for the electromechanical braking device is provided with a press device 12; and a first drive member 20 arranged to move the press device 12 while aligning the press device and a disc laminated body and apply brake pressure on the disc laminated body, and includes a second drive member provided with the piezoelectric assembly 23 suitable for adjusting the brake pressure applied on the disc laminated body. This constitution can arrange the piezoelectric assembly 23 inside the actuator to provide a fixed end 23B.
