  "textContent": "An electric brake device (16) includes a first slave piston (88b) which is housed in a cylinder body (82) and generates hydraulic pressure in a first hydraulic chamber (98b) by moving forward, a motor which transmits a driving force to the first slave piston (88b), and a restriction pin (102) which is inserted and secured to the cylinder body (82) in a direction perpendicular to an axial direction of the cylinder body (82) and restricts a backward position of the first slave piston (88b) when a hydraulic pressure is applied from an outside to the first hydraulic chamber (98b), wherein the restriction pin (102) is inserted and secured to the cylinder mechanism (76) in the direction perpendicular to the axial direction of the cylinder main body (82). Further, a clearance (204) is formed between an inner peripheral wall (83) of the cylinder body (82) and a first groove portion (202a) and second groove portion (202b) which are formed on an outer surface of the restriction pin (102). As a result, a transmission of a load from the restriction pin to the cylinder body is suppressed, and a deformation of a piston sliding surface of the cylinder body is prevented.",
