In the example shown in the drawing, the width dimensions of the contact piece portions 51d and 57e are substantially the same.
Further, as will be described later, when the contact piece portions 51d and 57e move relatively along the substantially circumferential direction of the holding shaft 57a, one of the contact piece portions 51d and 57e is more than the other holding shaft 57a so as not to interfere with each other. It is provided so that it may be located outside in the substantially radial direction. In the illustrated example, the contact piece 51d of the fixed portion 51B is provided so as to be positioned outside the contact piece 57e of the roller holding portion 57A in the substantially radial direction of the holding shaft 57a.

In the guide device 9B configured as described above, the side guide body 50B has the first roller 54B in contact with one of the first groove wall 65A and the second groove wall 66A, and the second roller 55B in contact with the other. It moves along the curved guide groove 61A. In the present embodiment, when the side guide body 50B moves, the urging direction of the rollers 54B and 55B by the urging mechanism 53B switches to the opposite side (reverses) in the middle portion of the curved guide groove 61A in the longitudinal direction of the groove. It is configured.
As shown in FIG. 10A, in a state where the side guide body 50 </ b> B is positioned in one linear groove portion 63, the contact piece portion 51 d of the fixed portion 51 </ b> B is positioned outside the longitudinal direction of the one linear groove portion 63. The contact piece 57e of the roller holding portion 57A is positioned on one side of the one linear groove 63 in the groove width direction. In this state, the contact piece 51d of the fixing portion 51B and the contact piece 57e of the roller holding portion 57A are relatively separated from each other in the generally circumferential direction of the holding shaft 57a. In this state, the opening angle between the second arm 53b that is in contact with the contact piece 51d of the fixed portion 51B and the first arm 53a that is in contact with the contact piece 57e of the roller holding portion 57A is 90 °. It is over 60 degrees (in the example shown, about 94 degrees). In this state, the roller holding portion 57A biases the fixing portion 51B so that the first roller 54B is pressed against the first groove wall 65A and the second roller 55B is pressed against the second groove wall 66A. It is urged around the holding shaft 57a by the mechanism 53B.

Further, when the side guide body 50B moves from the one linear groove portion 63 toward the curved groove portion 62, the contact piece portion 51d of the fixed portion 51B and the contact piece portion 57e of the roller holding portion 57A are held by the holding shaft. It moves in a relatively close direction along the substantially circumferential direction of 57a. That is, the opening angle between the second arm 53b and the first arm 53a gradually decreases.

Further, when moving in this way, the contact piece 51d of the fixed portion 51B and the contact piece 57e of the roller holding portion 57A overlap each other when viewed in the radial direction of the holding shaft 57a, and then the holding shaft 57a moves in a direction that is relatively separated along the circumferential direction. Thus, when each contact piece part 51d and 57e moves relatively, the opening angle of the 2nd arm 53b and the 1st arm 53a becomes large gradually, after becoming parallel. At this time, the urging directions of the rollers 54B and 55B by the urging mechanism 53B are switched to the opposite side (reversed). That is, the contact piece 51d of the fixing portion 51B is brought into contact with the first arm 53a and the contact piece 57e of the roller holding portion 57A is brought into contact with the second arm 53b so as to be the reverse of the above. The In this state, as shown in FIG. 10C, the opening angle between the second arm 53b and the first arm 53a is slightly less than 90 degrees (in the example shown, about 85 degrees). In this state, the roller holding portion 57A is urged against the fixed portion 51B so that the first roller 54B is pressed against the second groove wall 66A and the second roller 55B is pressed against the first groove wall 65A. It is urged around the holding shaft 57a by the mechanism 53B.

The urging direction is reversed and moves along the curved groove 62 in the same manner as described above.
The guide device 9B according to the present embodiment configured as described above also has substantially the same effects as those of the above embodiments. Further, the structure can be simplified as compared with the second embodiment.
In the present embodiment, when the side guide body 50B moves in the curved guide groove 61A, the rollers 54B and 55B are biased to the opposite side in the groove width direction almost always (other than when the side guide body 50B is reversed). However, the present invention is not limited to such an embodiment. For example, when the side part guide body 50B moves in the curved groove part 62, it is good also as a structure which does not substantially urge each roller 54B, 55B. That is, when the side guide body 50B moves in the curved groove 62, the first arm 53a and the second arm 53b are substantially parallel, and the restoring force by the urging mechanism 53B is applied to the roller holding portion 57A.
