Claims

[Claim for Utility Model Registration] A pair of left and right leaf springs that suspend two axles placed in the front and rear are attached to left and right spring saddles, respectively, and these spring saddles are swingable to a trunnion base via a spring shaft. In the trunnion suspension, the trunnion suspension has two threaded parts with the same winding direction and different thread diameters, and the larger diameter threaded part is inserted into the first threaded hole formed in the axis of the spring shaft. a first bolt that is screwed together; and a first bolt formed at the axis of the spring shaft.
a threaded portion that is screwed into a second threaded hole that has a larger diameter than the first threaded hole and has a different winding direction, and whose end surface abuts and locks the first bolt; and the spring saddle. a second bolt having a flange portion for locking in the axial direction of the spring shaft; and a bolt hole through which a threaded portion on the smaller diameter side of the first bolt passes; Screw into the threaded part,
A spring saddle locking structure comprising: a nut for preventing loosening of the second bolt;
