Claims

[Claim for Utility Model Registration] A main body fixed to the underframe near the wheel of the truck, a brake cylinder installed in the front and back direction of the main body, and one of the brake cylinders has a force point pin in the left and right direction on the piston rod of the brake cylinder. The other is rotatably supported by the main body via a fulcrum pin in the left and right direction, and is supported by a vertical lever that can swing freely around the fulcrum pin, and is supported by the lever via a spherical bearing. A push rod is loosely fitted into the front wall of the main body and protrudes forward, and is swingable in any direction around the spherical bearing, and the forward protrusion of the push rod is rotatable via a left-right direction connecting pin. A brake shoe head that is connected and has a brake shoe fixed to its front end; one end of the brake shoe head is rotatably connected to the brake shoe head via the connecting pin, and the other end is rotatable to the main body via a support pin in the left and right direction. A brake unit is equipped with a vertical hanging device that is supported by a support pin and is swingable about the support pin. A brake unit characterized by expanding in the vertical direction.
