<p>PURPOSE:To aim at simplifying the fabrication of a disc brake and miniaturizing thereof, by assembling members for transmitting the force of pistons to friction pads, to form the disc brake, and as well to aim at facilitating the assembly of the disc brake and enhancing the strength thereof, by forming a hook section for pressing a hold plate in a tie rod as one of the above-mentioned members. CONSTITUTION:When hydraulic pressure from a master cylinder is fed through a filling port 24M, pistons 25, 26 are moved in the opposite directions with respect to each other, so that a hold plate 21a is pressed by the end of the piston 25. Therefore, a friction pad 21 is made in press-contact with one of surfaces of a disc 20 while the end of the piston 26 presses the center section 27a of an arm 27 in the opposite direction so that a tie rod 28 is pressed in the same direction. Further a hold plate 29 is pressed against the other surface of the disc 20 while a friction pad 22 is made in press-contact with the other surface of the disc 20, resulting in braking. With this arrangement, a hook section 28b is formed in the front end part of the tie rod 28, for pressing a hold plate 29, thereby it is possible to facilitate the assembly of the disc brake and to enhance the strength thereof.</p> |
