PROBLEM TO BE SOLVED: To provide a guide device capable of manufacturing a support arm for supporting a guide pulley in an approximately co-using state and achieving the further reduction of manufacturing cost. SOLUTION: The guide device is provided with the guide pulley 31 engaged with a chain 27; the support arm 33 for rotatably supporting the guide pulley 31 through a pulley shaft 32; a unit case 35 as a mounting base mounted with the support arm 33; and a support shaft 34 for pivotably and pivotally supporting the support arm 33 on the unit case 35. A position restriction part 40 for restricting a pivot position of the support arm 33 is formed on the unit case 35 and a claw 33c engageable with the position restriction part 40 by being bent is formed on the support arm 33. Thereby, by a simple structure for only bending the claw 33c of the support arm 33 or not, a function for giving tension is given or is not given, to be put to a proper use. Thereby, one kind of a guide device 30 can be used in the approximately co-using state. COPYRIGHT: (C)2007,JPO&INPIT |
