ABSTRACT:
There is disposed a damper7, which provides a resistance to a retracting movement of a piston71. A door opening lever2has a pressing part2cformed with a cam surface, which is configured so as to have a distance from a swingable shaft2agradually increasing toward a cam end2e. The damper7is configured so that a piston rod72is fixed to a depth end of a housing9, that a gap9cis formed between an outer wall of the cylinder70and an inner wall of the housing9, and that the cylinder70has a depth end70aconstantly brought into press-contact with the cam surface2dof the door opening lever2under a biasing action. When the door opening lever2is not subjected to pulling operation, a portion of the cam surface2dclose to the cam end2eis brought into press-contact with the depth end70aof the cylinder70to retract the piston71into the cylinder70at the maximum.
