つている。 An example of a conventional shorhold nut fixing structure is shown in FIG. 1 is a bucking plate, 2 is a brake shoe, and 13 is a stud pin.
The stud pin 13 has one end fixed to the outer edge of the through hole 1a of the bucking plate 1 so as to protrude inwardly, and a threaded portion 13a at the other end inserted into a long hole 2a' provided in the brake shoe web 2a. . 14 is a shewhold nut, and a grooved nut is used. Reference numeral 15 denotes a stud pin, and the shoe hold nut 14 is connected to the threaded portion 13a of the stud pin.
The shewhold nut 14 is fixed to the stud pin 13 by screwing the stud pin 15 through the groove 14a of the shewhold nut 14 and the pin hole 13b provided in the stud pin 13.

に阻止されている。 In Figure 2, 1 is a bucking plate, 2
is a brake shoe, 2a is a brake shoe web, and 2a' is a long hole, which are the same as in the conventional example. 3
1 is a stud pin, and the distal end portion of the threaded portion 3a is notched in the axial direction to form a flat irregularly shaped portion 3b. As in the conventional example, the stud pin 3 has a flange 3c in contact with the inner edge of the through hole 1a of the backing plate, one end is crimped and pressed against the outer edge, and fixed and protrudes inward, and the threaded portion 3a of the other end is fixed. is inserted into a long hole 2a' provided in the brake shoe web 2a. 4 is a shewhold nut, and as shown in FIG. 3, its head is a polygonal locking part 4.
It is formed in a. 5 is a nut holder;
As shown in FIG. 4, it is a short cylindrical body with a bottom, and its inner peripheral surface 5a has a polygonal shape that can be engaged with the polygonal outer periphery of the locking part 4a of the shewhold nut while being restrained from relative rotation. A through hole 5b is formed in the center of the bottom and is made of a circular cast surface and a flat surface that is inserted into the tip of the threaded part 3a of the stud pin and restrains relative rotation.
is provided. The assembly procedure for these will be explained. Screw the shoe hold nut 4 onto the threaded portion 3a of the stud pin toward the brake shoe web 2a, and after adjusting the gap between the brake shoe web 2a and the shoe hold nut 4, tighten the nut holder 5.
is inserted into the tip of the stud pin 3 and engaged with the locking portion 4a of the shoe hold nut. Next, attach one side of the clip pin 6 to the threaded part 3 of the stud pin.
It is engaged with the thread groove a, and the other side is locked with the irregularly shaped part 3b of the stud pin. Therefore, the clip pin 6 prevents the nut holder 5 from moving in the axial direction, and the nut holder 5 engages with the irregularly shaped portion 3b of the stud pin to restrict its rotation. Since the relative rotation is restrained and engaged, the rotation is completely prevented.
なお、シユーホールドナツトの頭部に形成され

防止できる。 Note that the locking portion 4a formed on the head of the shuhold nut only needs to restrict relative rotation with the nut holder 5, and therefore may be formed to have a width across flats or the like. In addition, if the clip pin 6 is formed to be entirely curved as shown in FIG. 6, and is attached to the stud pin 3 with both ends in elastic contact with the nut holder 5, the buckling of the shoe-hold nut 4 can be eliminated and the nut holder 5 can be reliably prevented from wobbling.

ピンへの位置保定するクリツプピンとを有する。 The fixing structure of the shuhold nut according to the present invention is such that one end is fixed to the bucking plate and the threaded part of the other end is fixed to the stud pin which is inserted into the long hole of the brake web. A stud pin with a deformed part in which the distal end of the groove is notched in the axial direction, a shewhold nut with a locking part formed on the outer periphery and screwed onto the stud pin, and a locking part of the shewhold nut. A nut holder having a through hole that engages in a relatively unrotatable manner and is relatively unrotatably engaged with the irregularly shaped portion of the stud pin; It has a clip pin that holds the nut holder in position on the stud pin.
