<P>PROBLEM TO BE SOLVED: To provide a lid opening/closing link structure that allows one-hand operation from the time when lid opening operation starts to the time when its fully-opened state is held. <P>SOLUTION: In the lid opening/closing link structure, a retaining mechanism is provided in a four-joint link mechanism. The retaining mechanism comprises an engagement pin 37 projecting at the rear end of a second hinge arm 11, a support pin 26 projecting at the base end of an extension plate 18 of a link bracket 12, a hook bracket 27 rotatably supported at its center portion by the support pin 26 and a tension spring 36 pulling the hook bracket about the support pin 26 in the clockwise direction. The hook bracket 27 includes a slanted pressing portion 27a which is pressed to the engagement pin 37 with the lid opening operation and whose pressing position is relatively moved to the central direction as the hook bracket 27 is rotated counterclockwise about the support pin 26 while resisting the tensile force of the tension spring 36, and an engagement depression 33 engaged with the engagement pin 37 in the central direction of the slanted pressing portion 27a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
