  • Sliding device
    Patent number: 11890971
    Abstract: Provided is a sliding device which can avoid unintended locking release without depending on an excessive engagement force of an engagement member. The sliding device includes a lock mechanism that locks an upper rail to a lower rail. The lock mechanism includes: an engagement member that shifts in the upper rail between a locking position and a release position; a first urging member that gives an urging force to the engagement member in a direction from the release position to the locking position; and an operation member for shifting the engagement member from the locking position to the release position. The operation member comprises a shift restrictor that keeps the engagement member from shifting to the release position when the engagement member is in the locking position.
