号)。2. Description of the Related Art In a floating type brake disk, thermal expansion due to frictional heat during braking occurs only in a braking portion,
The braking part has an advantage that irregular heat distortion does not occur because of the ring shape, but since both members and the pin are separate bodies,
An impact is likely to occur between the pin and the pin during braking and driving. In order to alleviate this impact, a disc spring that presses against both members is generally fitted to the pin to restrict the free movement of both members. (For example, Jpn.
issue).

レーキディスクが高コストになる不都合がある。FIG. 4 shows an example of a brake disk of this type. A pin e is inserted into a concave portion b of a hub a and a concave portion d of a braking portion c, and a disc spring g and a washer are placed on a step portion f of the pin e. h and is fixed at the swaged portion i. However, in this type, there is a disadvantage in that the brake disk is expensive because the disc spring g is considerably expensive.

トの増加を招くことになる。In a brake disc of this type, the gap j between the hub a and the braking portion c is usually small as shown in FIG. 5A, and the circumferential gap k between the recess d and the pin e is normally small.
If the braking part c thermally expands due to frictional heat during braking,
As the diameter increases, the gap j increases as shown in FIG.
Since the circumferential gap k between the pin e and the concave portion d is also large, the impact is also large. In order to suppress the occurrence of the impact, the disc spring must be made strong, which leads to an increase in cost.
