Patent ID: 8151413

Claim:
A drawing device for imposing a biasing force in one direction to an opening/closing body movable relative to a frame when the opening/closing body moves in the one direction, comprising: a trigger pin which is attached to one of the frame and the opening/closing body; and a drawing device main body which is attached to an other of the frame and the opening/closing body and provided for catching the trigger pin to provide the opening/closing body the biasing force in the one direction, the drawing device main body having a base which is attached to the other of the frame and the opening/closing body and elongated in a moving direction of the opening/closing body, a slider which has a trigger catcher capable of catching the trigger pin and is slidable relative to the base in a longitudinal direction while the trigger catcher catches the trigger pin, an elastic member which spans the base to the slider, provides the biasing force so as to move the slider relative to the base in the longitudinal direction and thereby imposes the biasing force in the one direction to the opening/closing body, and a damper mechanism which generates a damping force against the slider moving relative to the base in the longitudinal direction by the biasing force of the elastic member, the damper mechanism having a first damper and a second damper as damper sources each for generating the damping force, a damper base which is provided in the base to be slidable in the longitudinal direction and a damper lock which is provided in the damper base, and which engages with the base so as to prevent the damper base from sliding relative to the base in the longitudinal direction and releases engagement with the base so as to make the damper base slidable relative to the base in the longitudinal direction, wherein when the slider moves relative to the base in the longitudinal direction by the biasing force of the elastic member, first the damper base engaging with the base by the damper lock moves relative to the slider thereby the first damper generating the damping force, and then, the damper lock and the base are disengaged and the base moves relative to the damper base and the slider, thereby the second damper generating the damping force.
