Claims

[Scope of utility model registration request]

a self-return spring wound around a shaft; a drive portion that rotates with the shaft and is capable of engaging an elastic leg of the self-return spring when the shaft rotates; and an elastic leg of the self-return spring when the shaft is at rest; A self-return structure for a shaft, characterized in that a locking member made of an insulating material is provided for elastically locking a leg.
