In the present embodiment, the detachment preventing portion 132 of the detachment prevention member 130 is attached to the wire groove 112 on the outer periphery of the pulley 110 only by fitting the detachment prevention member 130 to the protrusion 57 which is the detachment prevention member attaching portion. The wire 20 can be disposed at a position facing the portion wound in the middle of the two portions of the introduction portion and the lead-out portion in the radial direction.

Further, as the pulley 110, a pulley 110 having flanges or disk-like surfaces that are the same shape as the front and back surfaces of the pulley 110 with the wire groove 112 interposed therebetween can be used. That is, the pulley 110 has no front and back surfaces, and any surface on the front and back surfaces is arranged toward the guide rail 50 side, so that the surface becomes the guide rail side facing surface 114. Therefore, when the pulley 110 is attached to the guide rail 50 by fixing the pulley shaft 120 inserted through the pulley 110 in the fixing hole 55a of the fixing portion 55 of the guide rail 50, the orientation of the front and back surfaces of the pulley 110 is reversed.

The fixing portion 55B has a fixing hole portion 55a for fixing the pulley shaft 120, and a periphery of the fixing hole portion 55a on the distal end surface 57Ba.
In the come-off prevention member 130B, in the come-out prevention member frame 136B provided with the fitting portion 134B on the inner periphery, the come-off prevention portions 132 are erected from each of the opposing linear portions. The direction changing mechanism 100B can obtain the same effects as the direction changing mechanism 100. In particular, according to the direction changing mechanism 100B, when the fitting portion 134B of the come-off preventing member 130B is fitted into the fitted portion 572B of the come-off preventing member attaching portion 57B, the come-off preventing portion 132 disposed after fitting. Can be placed at an accurate position without adjustment for positioning the position at an accurate position (displacement prevention position).

In the present embodiment, the fitting portion 134 of the direction changing mechanism 100 is formed in a concave shape, and the fitted portion 572 of the direction changing mechanism 100 is formed in a convex shape. 134 may be formed in a convex shape, and the fitted portion may be formed in a concave shape that fits into the convex fitting portion. Examples of this configuration are shown as modified examples 3 and 4 in FIGS.

The direction changing mechanism 100C is provided with a groove portion 59 around the protruding portion 58 provided to protrude toward the pulley 110, and is formed in a concave shape, and a convex shape that fits into the locking member mounting portion 57C. And a locking member 130B having a fitting part 134C.
In the direction changing mechanism 100 </ b> C shown in FIG. 6, the groove 59 is formed adjacent to the projecting portion 58 and surrounding the projecting portion 58.
The fitting portion 134C is formed so as to protrude from the inner peripheral edge portion of the rectangular frame-shaped detent member frame 136C in which the detent portion 132C is erected on the outer edge of the detent member 130C toward the guide rail 50C. The wall surface on the outer peripheral side surrounding the fixed portion 55C in the groove portion 59 becomes a concave fitted portion 572C.
By fitting the fitting portion 134C into the fitted portion 572C of the groove portion 59, the come-off preventing member attaching portion 57C and the come-off preventing member 130C are fitted, and the come-off preventing member 130C is fixed to the fixing portion 55C. The rotation of the pulley shaft 120 around the axis is restricted.

[Modification 4]
