Provided is an electric brake device with a parking function, said device making it possible to implement a parking brake function in a space-saving manner. A parking brake mechanism (5), which generates a parking brake function using a friction material operation mechanism (3) that is driven by a main brake motor (4), is provided. The parking brake mechanism (5) has a parking brake motor (9) that is provided coaxially with one of rotating shafts (4c), (16), and (27) which transmit torque from the main brake motor (4) to the friction material operation mechanism (3). A linear motion mechanism (33), which moves a rotor (9a) of the motor (9), and an engagement mechanism (34) are provided. The engagement mechanism (34) is composed of a rotor-side engagement portion (34a) and a housing-side engagement portion (34b) that engages when the rotor (9a) advances to a prescribed position due to the linear motion mechanism (33). The engagement of the engagement mechanism (34) generates a pressing force holding function that holds the angle of the rotating shaft relative to the reaction force of the pressing force of the friction material (2). |
