Abstract
There is disposed a damper, which provides a resistance to a retracting movement of a piston. A door opening leverhas a pressing partformed with a cam surface, which is configured so as to have a distance from a swingable shaftgradually increasing toward a cam end. The damperis configured so that a piston rodis fixed to a depth end of a housing, that a gapis formed between an outer wall of the cylinderand an inner wall of the housing, and that the cylinderhas a depth endconstantly brought into press-contact with the cam surfaceof the door opening leverunder a biasing action. When the door opening leveris not subjected to pulling operation, a portion of the cam surfaceclose to the cam endis brought into press-contact with the depth endof the cylinderto retract the pistoninto the cylinderat the maximum.
