PURPOSE: To relax positioning accuracy at the time of assembling work by securing the outer end of a spiral spring for imparting a drag to a mover to an adjusting member which can adjust the position independently from the mover. CONSTITUTION: In an adjusting motor 15 for turning a mover 17 while resisting against the force of a spiral spring 32 secured to the mover 17 at the inner end 52 thereof, the spiral spring 32 is secured to an adjusting member 58 at the outer end 53 thereof. Position of the adjusting member 58 can be adjusted independently from the mover 17. For that purpose, a shaft 19 fixed with the adjusting member 58 can be turned, preferably, through a hexagonal hole 63, for example, regardless of the mover 17. According to the structure, force of the spiral spring 32 can be adjusted after assembling the motor 15 and the assembling accuracy can be relaxed. |
