ようになつている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a brake shoe holding device for a drum brake. Figure 1 shows a front view of a drum brake, where 1 is a leading brake shoe, 2 is a trailing brake shoe, 3 is a wheel cylinder 4 is an anchor, 5 is a drum, 6 is a strut, 7 is a shoe to shoe spring 8 2 respectively show bucking plates, and as shown in FIG. The anchor portion 9 is inserted into the drilled holes 8a and 1a.
At the same time as locking on the bucking plate 8,
The brake shoe is made to protrude from the brake shoe holding plate 1', and the saucer 11 and the spring 12 are sequentially fitted into the protrusion 10a, and the cup 13 is placed over the protrusion 10a.
3 to expose the tip of the pin 10, attach the stopper 14 to the tip, and then tighten the spring 12.
When pressed, the brake shoe 1 is held elastically.

ている。 In such a holding device, when the brake shoe is removed to inspect the brake or replace parts, the anchor portion 9 is held down from the bottom with your fingers, the cup 13 is pushed in, the stopper 14 is removed, or the third As shown in the figure, a special tool c is used to hold the cup 13 and check the stopper 14.
Since the brake shoes were removed and assembled using the special tool c, the work became complicated, and there were cases where it was not possible to hold down the pin 10 from the bucking plate side due to space constraints.
However, there were disadvantages such as extremely poor workability. The present invention was developed to eliminate these drawbacks, and as shown in Figure 4,
Above the anchor portion 16 of the pin 15 and with the pin 15 inserted and locked into the bucking plate 8, at a position below the brake shoe retaining plate 1',
A bulging portion 17 having a flat bottom is provided, and an elastic material 18 such as rubber, which is larger than the dimension between the bulging portion 17 and the bucking plate 8, is inserted between the bulging portion 17 and the bucking plate 8. , the pin 15 is elastically held by the bucking plate 8.

て有用なブレーキシユー保持装置を提供できる。 As described above, in the brake shoe holding device of the present invention, since the pin is elastically held on the bucking plate, unlike conventional devices, when removing or assembling the brake shoe, the anchor portion of the pin is held with fingers or the like. There is no need to hold down the brake, and even if there is no space, the work can be easily done without the need for special tools, and the elastic material has good sealing properties, making it extremely useful as it prevents muddy water etc. from entering the brake. A brake shoe holding device can be provided.
