Abstract

A method for manufacturing a shock absorber (1) disposed between a vehicle body member (41) of an automobile and a surface member including an interior or an exterior material (42) on a surface side of the vehicle body member and made up of a base portion (2) placed on the side of the vehicle body member or on the side of the surface member and a plurality of hollow frustum-shaped protrusions (3) protruding from the base portion toward the side of the surface member or toward the side of the vehicle body member, the method including: producing a forming mold (11) in which concave mold portions (13) for use to form the protrusions are provided in a flat portion (12) for use to form the base portion, wherein the forming mold is produced by additive fabrication by changing lamination pitch such that steps on flanks of the protrusions will become smaller toward tips of the protrusions to form stepwise inner surfaces in the concave mold portions; and subsequently introducing a heat-softened plastic sheet into the forming mold and vacuum-forming or pressure-forming the plastic sheet to make the flanks (31 to 33) on the protrusions (3) stepwise such that plastic thickness (d1 to d3) will decrease toward tips of the protrusions.
