問題が生じた。DISCLOSURE OF THE INVENTION However, considering that the recent market trend of washing machines has tended to increase in size, and it is necessary to brake a dehydration basket with a larger capacity, the conventional washing machine as described above is used. In the former case of the braking device of the machine, as the capacity of the dehydration basket increases, the drag force generated during braking also increases, so that the rising portion 20 alone cannot support the brake shoe 18 as shown by the arrow in FIG. It will move. For this reason, the contact surface of the brake shoe 18 with the brake wheel 16 is not evenly worn, but is worn one-sided, and the brake wheel 16 and the brake shoe 18 are not worn.
However, there was a problem that the braking performance deteriorated because the contact between the two was not uniform.

た。Further, in the latter case, the brake lever contact plate 24 must be caulked to the brake lever 21 by the rivet 25, which requires assembling man-hours. In addition, when the rising portion 23 and the inner surface 24a of the brake lever contact plate 24 are aligned and crimped, a jig or the like must be used, and it is difficult to align the both with high accuracy. Furthermore, since the contact surface between the brake shoe 22 and the brake lever contact plate 24 is smaller than the contact area between the brake shoe 22 and the rising portion 23, when the drag force during braking becomes large, the contact surface between the brake shoe 22 and the contact surface of the brake shoe 22 rises and falls. A difference occurs in the received drag force, the contact surface with the brake lever contact plate 24 having a small contact area is compressed, and the brake lever contact plate 24 is set into the brake shoe 22. As a result, the brake shoe 22 tilts and hits the brake wheel, causing one-sided wear, resulting in a decrease in braking force and deterioration in durability of the brake shoe 22.

Another object of the present invention is to provide a braking device for a washing machine capable of ensuring durability.

る。Therefore, even if a large reaction force is generated during braking, this reaction force is evenly distributed, and the braking portion does not tilt with respect to the brake wheel. Further, since a member for holding the brake lever is provided on the back surface of the braking portion, the braking portion can be easily attached and fixed to the brake lever by this member.

U at the tip of the so that it is perpendicular to the lever surface.
It is formed by bending it into a letter shape, and further comes into contact with the back surface of the braking portion, which will be described later. Reference numeral 3 denotes a brake shoe as a braking portion, which has an arcuate sliding surface and is integrally resin-molded with a claw portion 4 and the like for engaging the brake lever 1. The contact portion 2 at the tip of the brake lever 1 is provided with a hole 5 that engages with the claw portion 4 of the arc-shaped braking portion 3. By engaging the claw portion 4 and the hole 5, the brake lever 1 is clamped by the claw portion 4 provided on the back surface of the brake shoe 3, and the brake shoe 3 is easily attached. Reference numeral 6 denotes a relief portion which is formed on a side portion of the contact portion 2 and is provided so as to escape the claw portion 4 of the braking portion 3.

久性が確保できる。In the above structure, when the braking portion 3 is attached to the brake lever 1, the entire surface of the contact portion 2 contacts the entire back surface of the braking portion 3 as shown in FIG. The drag A (indicated by an arrow in FIG. 2) can be evenly distributed. For this reason, the braking force can be stabilized and durability can be secured without the braking portion 3 receiving the reaction force A and being inclined and worn.
