<p>PURPOSE: A brake device is provided to miniaturizing a guide structure of a moving member by directly forming a convex unit and a groove unit to the moving member and a supporting unit. CONSTITUTION: A brake device comprises a piston unit(8) and a wedge member(19). The piston unit comprises a piston cover(15), a piston(18), and a compression coil spring(20). The piston cover covers a piston opening unit(14) of a piston cylinder unit(12). A supplying unit(16) is formed at the piston cover to draw compressed air to the inside of the piston cylinder unit. The piston moves in the piston cylinder unit in a driving direction. The compression coil spring pressurizes the piston in the opposite driving direction. The wedge member is integrally mounted on the piston. The wedge member moves a moving member in the driving direction. The wedge member moves the moving member in a braking direction.</p> |
