。According to the return spring of the locking member in the seat slide device of the present invention, when the operating shaft is rotated against the biasing force of the spring, the coil portion is tightened, and the operating force of the operating shaft is loosened or When removed, the restoring force of the coil portion expands the diameter of the coil portion and rotates the operating shaft back.

コイル部の巻き締め時及び拡径時に、コイル部における
小径部は操作軸の外周に密接して、コイル部を安定よく
支持する。すなわち、コイル部が傾かないようにする。When the coil portion is wound tightly and expanded, the small diameter portion of the coil portion comes into close contact with the outer periphery of the operating shaft to stably support the coil portion. That is, the coil portion should not be tilted.

また大径部は、小径部よりも巻き締め量が大となって、
操作軸の回動角度の許容量を増大させる。Also, the large diameter part has a larger amount of tightening than the small diameter part,
Increase the allowable rotation angle of the operating shaft.
