特徴とするブレーキシユーのホールド装置。 A leaf spring bent into a substantially U-shape is placed on the brake shoe, and the enlarged portion at one end of the pin is engaged with the back plate, while the enlarged portion at the other end is engaged with the upper piece of the leaf spring. In a brake shoe holding device that urges the brake shoe to come into pressure contact with the back plate, a step with a lower height on the bending side is provided on the upper piece of the leaf spring, and the lower height is lowered on the bent side. A spherical recess corresponding to the hemispherical enlarged portion of the pin is formed in the portion, a through hole through which the shaft portion of the pin passes through the center of this recess, and a through hole larger than the outer diameter of the hemispherical enlarged portion is formed in the higher portion. A brake shoe holding device, characterized in that a hole is formed, and a passage is provided between the two holes, through which a shaft portion of a pin can move.
