Damper device

A damper device provided between a fixed body having an opening portion and an openable and closable body mounted on the opening portion of the fixed body so as to be opened and closed and configured to apply a braking force to the openable and closable body when the openable and closable body is opened and closed relative to the opening portion, the damper device having:

• an elastic resin member mounted on a projecting portion provided on the openable and closable body;
• and a receiving recess portion provided on the fixed body to receive the elastic resin member movably,
• wherein the elastic resin member includes:
• a base portion having a fitting portion in which the projecting portion fits;
• a pair of arm portions extending from an outer circumference of the base portion and capable of deforming elastically;
• a bridge portion coupling together distal end portions of the pair of arm portions directly or via the base portion and configured to deform elastically as the pair of arm portions deforms elastically;
• and
• a stopper configured to be brought into abutment with the receiving recess portion to restrict the openable and closable body from opening when the openable and closable body opens,
• wherein the base portion, the pair of arm portions, the bridge portion and the stopper are formed integrally, and
• wherein the receiving recess portion includes:
• an introducing portion configured to come into abutment with the pair of arm portions to bend the pair of arm portions diametrically towards each other;
• and a restricting portion configured to come into abutment with the stopper to restrict the openable and closable body from opening, the introducing portion and the restricting portion so functioning when the openable and closable body opens to cause the elastic resin member to move.
