Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To posture-displace a moving regulating portion to a regulating position even if the driving of driving means is stopped.SOLUTION: A ratchet gear 90 is displaced in conjunction with either one of a first support member 20 and a second support member 60. A first ratchet claw member 100 and a second ratchet claw member 101 are arranged so as to be displaced between a regulating position at which the ratchet claw members can be engaged with the ratchet gear 90 to regulate the displacement of the ratchet gear 90, and a permitting position at which the ratchet claw members are separated from the ratchet gear 90 to permit the displacement of the ratchet gear 90. A holding mechanism is equipped with a first linkage member 105 which connects the first ratchet claw member 100 and a first eccentric cam 115, and can be elastically deformed so as to energize the first ratchet claw member 100 toward the regulating position; and a second linkage member 106 which connects the second ratchet claw member 101 and a second eccentric cam 116, and can be elastically deformed so as to energize the second ratchet claw member 101 to the regulating position.SELECTED DRAWING: Figure 5
