Abstract

PURPOSE:To reduce the fluctuations of a wire inclination angle and a path length to prevent abnormal sound generation by allowing a turn pulley which transmits the rotary force of a driving pulley to a travelling member by means of a wire, to slide longitudinally along a support shaft. CONSTITUTION:When a driving pulley 14 rotates, one end part of a wire 18 is wound in and the other end part of the wire 18 is delivered out to cause the wire 18 to be shifted so that a travelling member 10 is subjected to linear reciprocating motion along guide shafts 11, 13. A wound position of the wire 18 changes in the longitudinal direction of the driving pulley 14 following the rotation of said pulley 14, and accompanied with this change turn pulleys 16, 17 move along support shafts 16a, 17a in the changing direction of the rolled position of the wire 18 at the driving pulley 14 from the wire 18. Consequently, even if the rolled position of the wire of the driving pulley changes, the abnormal sound is not produced since little changes in the inclination angle and the path length of the wire is obtained.
