Abstract: A housing of brake device includes a first oil path, a second oil path that is adjacent to the first oil path in a first direction along an axial direction of the first oil path and has a larger cross-section orthogonal to the axial direction than the first oil path, a third oil path connected to the first oil path, and a fourth oil path connected to the second oil path. A throttle member of the brake device is anchored to the housing by being press-fitted into the first oil path. The third oil path connects the fourth oil path through the throttle. When the throttle member moves in the first direction by releasing the press-fitting, the third oil path connects the fourth oil path through a gap between an inner circumferential surface forming the second oil path and an outer circumferential surface of the throttle member.
