PURPOSE:To guide wire smoothly and reduce noise following the drive of the wire by composing a guide cylinder having the wire inserted of an outer cylinder of metal and an inner cylinder of synthetic resin. CONSTITUTION:A drum 4 is fixed at a worm wheel 3b, and the middle part of a flexible wire 5 is wound around this drum 4. Guide cylinders 6 are installed on both sides of a worm speed reducing mechanism 3 respectively. The end sides of the wire 5 are inserted through the guide cylinders 6 and guides 7 respectively. Each guide cylinder is formed of an outer cylinder 6a of metal such as an iron pipe or the like fixed at a drive base 1 by weld or the like, and an inner cylinder 6b of synthetic resin applied covering the whole inner surface of this outer cylinder 6a. |
