どしたことを特徴とするものである。This invention reduces the wall thickness of the voice part and prevents the occurrence of surface sink marks on the part corresponding to the boss part on the surface of the side part during injection molding of the hamper. We provide a bumper side structure that prevents the tip of the boss from chipping or cracking in the tip even if the boss is made thinner. In order to achieve this object, the present invention extends a reinforcing rib across the boss part and the side part, and extends it to the vicinity of the tip of the boss part. and fit the bar link cylindrical part provided at the edge of the screw insertion hole of the bracket (4 bracket 1-) onto the outer periphery of the tip of the boss part, and bring the reinforcing ridge into contact with the bracket bracket 1-. It is characterized by a pambasite structure in which the boss part is reinforced.
