PROBLEM TO BE SOLVED: To provide an automatic warehouse to travel a transfer and place device such as a mobile carriage and a stacker crane by engaging a driving pulley with a timing belt and capable of preventing removal from the driving pulley and tooth flying of the timing belt due to jumping of the timing belt. SOLUTION: The driving pulley 15 is covered with a guide body 20 from above, and presser rollers 19 are arranged on both sides sandwiching the driving pulley 15 between them. It is possible to prevent removal and tooth flying of the timing belt 12 for travelling as floating of the timing belt 12 for travelling is avoided by the guide body 20. COPYRIGHT: (C)2003,JPO
