A vehicle shock absorber by which a uniform shock absorbing property can be obtained in all positions on a shock receiving surface and, particularly, a further uniform shock absorbing property can be obtained if the distance from the lower end of a recessed groove in a first wall to a second wall is made equal to the distance from the lower end of the recessed groove in the first wall to the lower end of a recessed groove in the second wall. A vehicle shock absorber ( 1 ) is installed inside a vehicle component part so as to absorb shocks from interior or exterior. The vehicle shock absorber ( 1 ) is formed hollow by blow-molding thermoplastic plastic. A first wall ( 2 ) and a second wall ( 3 ) are spaced from and opposed to each other. A shock receiving surface ( 4 ) connects the first and second walls ( 2, 3 ). The first and second walls ( 2, 3 ) are formed with pluralities of recessed grooves ( 5, 6 ) at substantially equally spaced intervals. The recessed grooves ( 5, 6 ) are disposed substantially normal to the shock receiving surface ( 4 ).
