The brake device (10, 30) includes an acquiring unit (22) for acquiring driving information regarding driving of the motor (11), a travel distance calculating unit (23) for, based on the acquired driving information, calculating a travel distance by which a brake block (14) travels to touch a tread surface (2A) of the wheel (2), and a wear amount calculating unit (24) for calculating a wear amount of the brake block (14) based on a currently calculated value of the travel distance and an old value of the travel distance.",
