である。 However, in conventional disc brakes of this kind, the guide pin is fixed to the caliper via the threaded member, so that each of the non-circular flange portions of the pair of guide pins is perpendicular to the direction of extension of the guide pin. Because this is done by locking to the detent locking portions located on different sides or directions with respect to the locked portion of each flange in the plane, the distance between the screwed guide pins is It was difficult to avoid that the distance would deviate slightly from the distance between the guide holes. This is between the bolt as a screwing member and the through hole of the caliper into which the bolt is inserted, or between the outer periphery of the guide pin fixed to the caliper via the screwing member and the locking member and the caliper into which the guide pin is fitted. This is because it is inevitable that some clearance will occur between the inner periphery of the through hole and the inner periphery of the through hole.

利点を有する。 Therefore, the locked portions of the pair of guide pins are brought into contact with the corresponding locking portions, and the threaded members are respectively inserted into the pair of through holes provided in the other of the carrier and the caliper. When screwing together the guide pins respectively received in a pair of guide holes provided in one of the two, these threaded members are connected to a locking member provided on the same side of the locked part as compared to the locked part. Since each member is rotated about a single point of contact with the other member, the clearance created between the shaft of one threaded member and its corresponding through hole and the shaft of the other threaded member. The clearance created between this and the corresponding through-hole points in the same direction, and at the same time, the distance between the center of one through-hole and the center of the shaft of the corresponding threaded member is the same as that of the other. The distance between the center of the through hole and the center of the corresponding shaft portion of the threaded member is kept equal. Therefore, the distance between the centers of the shaft portions of the two screwing members and the distance between the centers of the two through holes are kept the same. Further, the distance between the centers of the shaft portions of the two screwing members and the distance between the centers of the two guide pins are kept the same,
Furthermore, the distance between the centers of the two through holes and the distance between the centers of the two guide holes are also kept the same. Therefore, the distance between the centers of the two guide pins and the distance between the centers of the two guide holes can be kept the same, and the sliding of these guide pins in the corresponding guide holes can be performed reliably and easily. This has the advantage that parallel movement relative to the carrier can be performed reliably and easily, and braking can be applied reliably.

いう利点をも有する。 Furthermore, in the disc brake of the present invention, since the pair of guide pins is prevented from rotating by making the locking part and the locked part contact each other only at one place, it is possible to prevent the pair of guide pins from rotating at two or more places. It also has the advantage that the probability of keeping the center-to-center distance between the two guide holes and the center-to-center distance of the two guide pins the same, that is, the probability of achieving parallel movement of the caliper with respect to the carrier, is higher than in the case where this is done.
