PURPOSE:To form guide rails showing smoothness even if an angle is formed between rails, by fixing flexible guide rails to the joint part for connecting rails while forming the joint lapped over the guide rails fixed to the rails. CONSTITUTION:When rails 93 are revolved over an angle theta around a shaft 95 in order to bend guide rails at an angle theta, each of the guide rails 82 of a joint part is deformed so as to have the large radius of curvature R. In this case, rods 88, 88 integrated with support blocks 86 are slid while guided by support blocks 89 and support blocks 94 and both ends of the guide rails 82 are varied in the lap amount with guide rails 83 (for example, the inside guide rails 82 are increased in the lap amount as compared with the straight state thereof) and the deformation components of the guide rails 82 are absorbed to form the smooth guide rails along with the guide rails 83. |
