PROBLEM TO BE SOLVED: To improve strength as compared with conventional strength, and to reduce manufacturing cost while reducing weight by adopting a hollow structure in a trunnion shaft. SOLUTION: The trunnion shaft 14 is journaled by a trunnion bracket 4 between a pair of axles arranged in tandem at front and rear sides, and rotatably supports a leaf spring for supporting the axles on the front and rear sides via a rotation base. A cut hole 15 of a dead end type is formed by being drilled from an end at the vehicle widthwise inside (a right side in Fig.1) toward an end at the vehicle widthwise outside (a left side in Fig.1), and the end at the vehicle widthwise outside is left as a lid body in a non-opened state.
