Abstract

PURPOSE: To obviate the disengagement of a drive wire from pulley by providing such a pulley cover as the one with which spacing becomes smaller than the diameter of the drive wire.
CONSTITUTION: A pulley 8 on which a wire 9 is put on is supported rotatably about the shaft 11 secured to part of a reciprocating optical system. The wire 9 is led to the rotators 12, 13 having groove parts in the position slightly away from the pulley 8 so that it is connected to the drive part or body. A pulley cover 14 is fitted and supported by the shaft 11, on the outside of the pulley 8 and part 141 of the pulley cover 14 forms the cylindrical part 141 concentrical to the pulley cover 8 and its inside diameter is formed larger by a size d2 than the outside diameter of the pulley 8. The size d2 is of the value smaller than the wire diameter of the drive wire 9. This obviates the disengagement of the wire 9 even if it should try to disengage from the groove of the pulley 8.
