ABSTRACT:
A truck described herein comprises a movable loading table, energy absorber means and energy transmission means. The loading table is mounted on a body frame of the truck in such manner that it may move in the forward direction along said body frame when an impact force larger than a predetermined value is applied to a vehicle body of said truck. The energy absorber means is interposed between said body frame and said loading table for absorbing kinetic energy possessed by said loading table. The energy transmission means has its front end connected to a front bumper and is provided with an end portion located behind the cabin of the truck so as to be positioned in the path of said moving loading table. The energy transmission means is mounted on the body frame of said truck in such manner that it may move in the forward or backward direction along said frame body when an impact force larger than a predetermined value is applied thereto. The energy transmission means is mounted on the frame body by a bolt fixedly secured to either said energy transmission means or said body frame and extending through a center of a slot formed in forward and backward directions in the other of said transmission means or body frame to couple both of said members together. Upon movement of said energy transmission means in the forward or backward direction, said bolt is adapted to expand the slot, resulting in its plastic deformation.
