PURPOSE:To prevent a cargo from being squeezed or destroyed when a vehicle collides by arranging shock absorbers provided with many notch holes on the side face of hollow multiple-angle trapezoidal pillar bodies on the front bumper support section and front and rear sections of a cargo loaded on a bed. CONSTITUTION:When a cargo 2 loaded on a bed 1 is to be transported while safety against a car collision is secured, patch metals 3 are put at corners of the cargo 2 and bound by stretching a rope 4 with a wrench or the like. In addition, shock absorbers 5 converting the momentary high-load shock energy into a timewise-constant load via the buckling phenomenon and absorbing it are arranged on the fitting section of the front bumper 7 of a car body frame 6 and between the cargo 2 and the front guard frame 12 of the bed 1 and a rear roll bar 13. This shock absorber 5 is constituted by providing many notch holes 9 on the side face 8 of a hollow multi-angle trapezoidal pillar body.
