ブレーキ。 A cup-shaped piston is fitted into a cylinder formed in the caliper so as to be slidable in the axial direction via a piston seal, and this piston is pushed by a parking brake mechanism or pressurized fluid supplied into the cylinder. In the disc brake with a parking brake mechanism configured to press a pad by pressing the pad, the parking brake mechanism is slidable in the axial direction within a mounting hole provided in the bottom wall of the cylinder coaxially with the piston. A clutch member is fitted in a liquid-tight manner and is pushed axially toward the pad by a pushing means provided on the back; a first adjusting body that is movable by a predetermined gap and non-rotatable; and a first adjusting body that is provided between the first adjusting body and the clutch member, is screwed to the first adjusting body, and is separably engaged with the clutch member. a second adjusting body whose rotation is regulated by the clutch member; a return spring that biases the second adjusting body in the axial direction toward the clutch member; and a return spring that urges the second adjusting body from the first adjusting body A disc brake with a parking brake mechanism, characterized in that it is configured to include a spiral spring capable of rotating one or more revolutions in a protruding direction.
