Claims

[Scope of utility model registration request]

Engage the center bottom of the U-bolt with the leaf spring,
In a leaf spring type suspension in which an axle case and a leaf spring are connected by the U-bolt, the wall thickness of the center bottom of the U-bolt in the direction perpendicular to the circumferential surface of the leaf spring is greater than the wall thickness in the longitudinal direction of the leaf spring. A leaf spring type suspension structure characterized by a large spring.
