<p>PURPOSE:To prevent increasing of sliding resistance due to rust by providing first and second engagement grooves on one end of a caliper and rotating regulation position of a rotating regulation means around a support pin of the caliper, and a resin pin which engages with them. CONSTITUTION:A caliper 15, being supported to one end of a fixation support body 10 by means of a support pin 20, are arranged rotatably around the support pin 20 and slidably in an axial direction of a disc rotor 13. A first engagement groove 15b is formed on an end opposite to the support pin 20 in an axial direction of the disc rotor 13. The caliper 15 is held by the fixation support body 10 by means of a resin pin 21. A second engagement groove 10c is formed on the fixation support body 10 correspondingly to the first engagement groove 15b of the caliper 15. The pin 21 is engaged with the engagement groove 10c and 15b, for regulating rotation of the caliper 15 in an outer diameter direction. The rotation regulating means is simply made up of the first and second engagement grooves 10c, 15b and the pin 21. The pin 21 is free from rust, so that the caliper 15 is prevented from being increased in sliding resistance.</p> |
