PURPOSE:To improve the travel stability by providing a linear section and an arched section in a guide for an endless rotary body and making the arched section wider than the linear section. CONSTITUTION:A guide 7 for an endless rotary body is constructed with arched sections 8b, 8c arranged at one ends by approximately 180 deg. along the outercircumferential edges of drive and drive wheel members 1, 3 and a pair of linear sections 8a coupling between said arched sections. While a load containing frame guide 8 is constructed with a pair of linear sections arranged in parallel between the drive wheel member 1 and th driven wheel member 3 and tne one and the other side arched sections 8b, 8c of approximately 180 deg. wider than said linear section having the centers on the axes of the drive and driven wheel members 3. With such structure, even upon expansion of the endless rotary member, the load containing frame members will never collide each other nor slipped from the guide resulting in improvement of the travel stability. |
