摘要： PROBLEM TO BE SOLVED: To provide a headrest of a vehicle seat which is capable of suppressing the play of a headrest body at a using position.
SOLUTION: The headrest 1 of the vehicle seat includes a base body 2, the headrest body 3 supported by the base body 2 so as to be tilted, an urging spring 6 for urging the headrest body 3 from the using position to a tilted position, and a lock mechanism for locking the headrest body 3 at the using position, and between the base body 2 and the headrest body 3, a shaft member 5 which tiltably connects them is provided. The spring member 6 has a coil part 6a wound around the outer periphery of the shaft member, a fixed end part locked to the base body 2 and a turning end part 6c locked to the headrest body 3. The diameter of the coil part 6a is set to a size to be narrower than the diameter of the shaft member 5 when the headrest body 3 is at the using position and to be larger than the diameter of the shaft member 5 when the headrest body 3 is at the tilted position.
