Summary:PROBLEM TO BE SOLVED: To prevent an excessive force from acting on a linkage mechanism even if a load is applied to an inclinable direction with respect to the other striker in a state that an inclinable operation of one of the strikers is limited.SOLUTION: In a lock structure 26 for locking legs of a popup seat of a vehicle to a floor, two inclinable strikers 35A, 35B to which the legs of the seat in inclinable positions are locked in inclinable positions are arranged at the floor. A linkage mechanism 36 which makes both strikers 35A, 35B perform inclinable operations in conjunction with each other is arranged between the two strikers 35A, 35B. A block mechanism 70 which blocks a linkage operation between both strikers 35A, 35B when a load to an inclinable direction is applied to the other of the strikers 35B, 35A in a state that the inclinable operation of one of the strikers 35A, 35B is limited is arranged at the linkage mechanism 36. 【課題】いずれか一方のストライカの起倒動作が制限された状態で、他方のストライカに対して起倒方向への荷重が掛けられた場合でも、連動機構に無理な力が作用するのを防止することができる。【解決手段】車両における跳ね上げ可能なシートの脚をフロアに掛止するための掛止構造26において、フロアには起立位置においてシートの脚が掛止される2つの起倒可能なストライカ35A,35Bを設ける。2つのストライカ35A,35Bの間には、両ストライカ35A,35Bの起倒動作を連動して行わせる連動機構36を設ける。連動機構36には、いずれか一方のストライカ35A,35Bの起倒動作が制限された状態で、他方のストライカ35B,35Aに対して起倒方向への荷重が掛けられたとき、両ストライカ35A,35Bの間の連動動作を遮断する遮断機構70が設けられている。【選択図】図3
