接触しなくなり、偏摩耗や不快な摺擦音を生じ易い。Conventionally, this type of device is described in Japanese Utility Model Publication No. 155/1983, in which a fixed friction pad is fitted into a recess provided on the - side of the second arm of the caliper. A device is known in which the elastic support plate is fixed to the other side of the second arm in a non-rotatable manner using bolts, but in this case, the fixed friction pad is prevented from rotating during braking. The fixed friction pad is eccentrically bolted to the elastic support plate, so when rotational force is applied to the fixed friction pad during braking, the elastic support plate is twisted and the braking surface of the fixed friction pad is tilted, causing rotation of the brake disc. It does not contact the surface evenly, which tends to cause uneven wear and unpleasant rubbing sounds.

たことにある。Therefore, the present invention securely holds the fixed friction pad on the second arm of the brake caliper so as to prevent it from rotating during braking, thereby preventing uneven wear of the fixed friction pad and generation of unpleasant rubbing noise. In addition, the object of the present invention is to provide a fixed friction pad mounting device for a disc brake, which has a simple structure and allows for easy installation and replacement of the fixed friction pad, and its features include: The second arm has a recess opening on the negative side of the second arm, a mounting window opening on the bottom of the recess, and communicating with the inside of the mounting window on the other side of the second arm. and a pair of locking grooves opening in the recess, and elastic mounting in which both ends are locked in the pair of locking grooves on a locking pawl protruding from the back surface of the fixed friction pad that is fitted into the recess. The intermediate part of the rod is locked so that the fixed friction pad is pressed against the bottom surface of the recess by the elasticity of the mounting rod, and furthermore, the locking piece protruding from the outer periphery of the fixed friction pad 2 is attached to the bottom of the recess. This is because it engages with a locking groove formed on the side wall.
