(Fig.) Alternatively, a stepped engagement base 2 may be provided and the outer pad back plate 4 may be integrally riveted with the outer pad 3 as a wear material.
It is formed by providing an engagement protrusion 5 that fits into the engagement base 2 in a grooved or stepped shape, and is used to control the vertical positioning of the outer pad 3 and the outer pad back plate 4, and the position of the outer pad 3 and the outer pad during braking. It is formed to control the sliding guide of the back plate 4.

を併合する。Problems to be solved by the invention As in the conventional example, in the engagement method by fitting the engagement base 2 of the caliper 1 and the engagement protrusion 5 of the outer pad back plate 4, it is difficult to engage the engagement base 2. The contact surface of the protrusion 5 takes charge of all the torque during braking and the movement friction of the outer pad back plate 4. In addition, collisions of the contact surfaces due to vibrations that occur during braking and when the vehicle is running can cause the contact surfaces of the engagement protrusions 5 to wear out or deform retrogradely, causing the engagement between the caliper 1 and the outer pad back plate 4 to become loose. There is a problem that the outer pad 3 and the outer pad back plate 4 may fall off due to misalignment. In addition, in order to eliminate the gap at the fitting part between the engagement base 2 and the engagement protrusion 5, improve the fitting precision, and deal with the above-mentioned problems, the fitting part should be machined with high precision. need to be formed. However, this machining in difficult-to-machine positions has poor workability and has problems that are difficult to apply to actual products.

ものである。Means for Solving the Problems This invention provides a pad holding fitting so that the outer pad 3 and the outer pad back plate 4 are suspended from the engagement base 2 of the caliper 1 to prevent them from coming off. In addition, we have developed a pad holding fitting for disc brakes that solves the above-mentioned problems by absorbing the vertical "backlash" with the elastic force of the pad holding fitting and preventing "sound generated" during braking. The purpose is to provide

る。 The caliper 1 is held on the brake base 9 by a slide pin 10 fixed to the brake base 9. During braking, the caliper 1 slides on the slide pin 10 to sandwich the disc rotor 6 rotating between the inner pad 7 and the outer pad 3. Configured to brake. That is, during braking, the piston or extrusion rod is pushed out by air pressure, hydraulic pressure, or screw force and pushes the inner pad back plate 8, pressing the inner pad 7 against one braking surface of the disc rotor 6, and at the same time, the reaction force is The caliper 1 moves in the opposite direction to the pressing force, pushes the outer pad back plate 4, presses the outer pad 3 against the other braking surface, and is sandwiched between the outer pad 3 and the inner pad 7 to generate a braking force. There is. In this case, the inner pad back plate 8 is
It comes into direct contact with the piston or extrusion rod and receives strong pressing force. However, since the outer pad back plate 4 receives a pressing force from the protruding wall portion 11 of the caliper 1, the engagement base 2 of the caliper 1 and the engaging protrusion of the outer pad back plate 4 are related to the strength of the protruding wall portion 11. The slight "backlash" in No. 5 grows and causes noise and accelerates damage to the pads.

As shown in FIG. 7, the side end portions 13 are formed by bending a width-like thin steel plate and are slightly wide at both ends.
14, and rectangular through holes 15, 16 having long sides in the longitudinal direction are provided approximately at the center of the side ends 13, 14. Further, a gripping portion 17 is provided in the center portion to which the engaging protrusion 5 of the outer pad back plate 4 is riveted, and the gripping portion 17 is made to protrude in a direction opposite to the gripping piece portion 18.
It is formed into a convex surface that approximates the outer peripheral edge of the outer pad 4. Furthermore, as shown in FIG. 7, the gripping portion 17 includes a substantially rectangular protruding piece formed so as to protrude from both sides of the width plate forming the pad holding fitting 12, and an elastic portion 19 having a convex surface outwardly on both sides. are formed by bending them at approximately right angles, and the edge portions are formed parallel to each other, and two pairs of riveting holes are provided at spaced apart positions on the same line. do.

として力の方向に移動する。 In this case, the spacing between the gripping pieces 18 is set to a size that allows the outer pad back plate 4 to fit slightly loosely. The outer pad back plate 4 is formed into a fan shape having inner and outer peripheral edges curved in an arc shape, and a width plate-shaped engagement protrusion 5 protrudes radially from the outer peripheral edge with the midpoint of the outer peripheral edge as the midpoint. Form. The engaging protrusion 5 is integrally formed with the outer pad back plate 4 and has the same thickness. As shown in FIG. 9, the outer pad back plate 4 and the outer pad 3 provided with the pad holding fittings 12 are fitted so that both side edges of the engaging protrusion 5 are slightly loosely fitted to the opening edges of the caliper 1. Side end 13 of pad holding fitting 12,
14 is placed on the engagement base 2 and engaged. Therefore, when the outer pad back plate 4 receives a pressing force from the protruding wall portion 11 of the caliper 1 during braking, the outer pad back plate 4
The contact surface between the caliper 1 and the engagement base 2 is used as a sliding surface to move in the direction of force.

となる。 Since this invention is formed as claimed in the utility model registration based on the above-mentioned embodiment, there is no possibility that the outer pad will fall off. Also, due to the elastic force of the pad retaining metal fittings, there is so-called "backlash" in the vertical direction.
Since the noise is absorbed, it is possible to eliminate the noise caused by rattling during braking or while the vehicle is running. In addition, there is no need to perform highly accurate machining to form the engagement base, and the pad holding fitting is also formed by flat plate processing, so it is easy to form and can be formed lightweight, providing a practical pad holding fitting. becomes possible.
