Vehicle seat

A vehicle seat comprising:

• a slide rail including a lower rail disposed on a vehicle component side, and an upper rail disposed on a seat body side and supported by the lower rail so as to be movable in a sliding manner;
• and
• a slide lock mechanism that regulates a slide movement of the upper rail relative to the lower rail in an appropriate position, wherein:
• the slide lock mechanism includes a locking member that regulates the slide movement of the upper rail in the appropriate position as a slide lock state, and an operating member that transmits, to the locking member, a release control force to release the slide lock state of the locking member;
• the locking member includes a first biasing member that maintains the slide lock state of the locking member in an elastically biasing manner;
• the operating member includes a second biasing member to bias the operating member to an initial position in which an operation of the operating member is not started;
• when a biasing force of the first biasing member is compared with that of the second biasing member, the biasing force of the first biasing member is set larger than that of the second biasing member;
• a clearance is set for the operating member between the initial position and an operation position in which the release control force is applied thereto against the biasing forces of the first biasing member and the second biasing member so that the slide lock state of the locking member is released;
• the operating member includes an operation input member that inputs the release control force, and an operation output member that outputs the release control force;
• the second biasing member is provided between the operation input member and the operation output member so that the operation input member is connected to the operation output member so as to be movable relative to each other;
• the clearance is provided between the operation input member and the operation output member;
• and
• the initial position is set by retaining the clearance between the operation input member and the operation output member by the second biasing member.
