A frame mounting structure of a frame body vehicle is provided to prevent the mounting bolt from being damaged even if large load is applied to the mounting bolt by breaking the fixing pin and rotating the head of the mounting bolt. In a frame body vehicle, a chassis frame(110) is assembled to a body frame(130) with a mounting bolt(140) by interposing upper and lower bushes(122,121) to the chassis. A head(141) of the mounting bolt is shaped like a sphere, and a rotary housing part(150) is fixed by making the head of the mounting bolt received in the body frame. The head is fixed by a fixing pin(142) penetrating the housing part. The head of the mounting bolt is rotated in the housing part if the fixing is broken by impact. The housing part has upper and lower housing parts(151,152) mutually welded.
