The width dimension W3 of the connection guide portion 61 in the Y direction is smaller than the dimension W4 between the outer skins 2 in the Y direction. Therefore, the slider 1 as a whole does not interfere with the skin 2 during its travel.

[Operation of this embodiment]
The operation of the slider 1 according to this embodiment will be described below.
First, a case will be described in which the connected fastener stringers 3A and 3B are separated.
First, the slider 1 is moved in the -X direction with respect to the left and right element rows 32. By this traveling, the left and right element rows 32 in the connected state (engaged state) shown in FIG. 6 are guided from the connection guide section 61 to the separation guide section 51.

In the separation guide section 51, the Y-direction inner portions of the left and right element rows 32 are in sliding contact with the separation guide surface 55, and this portion is lifted by the separation guide surface 55 in the +Z direction. When lifted in this manner, the left and right element rows 32 are separated from each other while being in an inclined state as shown in FIG. 7 in which the inner portions in the Y direction are located on the +Z direction side than the outer portions in the Y direction. Further, the separated left and right element rows 32 are restricted by the lower surface 541 of the restriction piece portion 54 of the separation guide portion 51 so as not to rise excessively in the +Z direction.

The separated left and right element rows 32 come out from the shoulder side of the slider 1. As mentioned above, the slider 1 separates the left and right element rows 32 by running in the -X direction, so compared to, for example, a slider that does not raise the left and right element rows 32 upwards at all and separates them only in the Y direction. Therefore, the opening width dimension in the Y direction of the separated left and right element rows 32 can be reduced.
Furthermore, in this embodiment, the left and right sides of the separation guide section 51 are open spaces 58 as described above, and are not provided with a flange section or the like that guides the separated left and right element rows 32 in the X direction. The Y-direction dimension of the slider 1 can be made smaller than that provided with such a flange portion.
For this reason, the position where the fastener tape 31 is sewn onto the outer skin 2 is set closer to the element row 32 side in the Y direction, and the dimension of the fastener tape 31 in the Y direction from the front side, that is, the visible width W5 in the Y direction (Fig. Even if the size of the slider 1 is small, it is possible to reduce the risk of the slider 1 interfering with the outer skin 2 and the threads used to sew the outer skin 2 and the zipper tape 31 together, thereby suppressing the deterioration of the outer skin 2 and the like due to interference and the running resistance of the slider 1. be able to.

Second, a case will be described in which the separated fastener stringers 3A and 3B are connected.
First, the slider 1 is moved in the +X direction relative to the left and right element rows 32. By this traveling, the left and right element rows 32 in the separated state shown in FIG. 7 are guided from the separation guide section 51 to the connection guide section 61.

The element row 32 guided to the connection guide section 61 is pressed in the −Z direction by the holding surface 421 and supported by the bottom surface 621, and is changed from the inclined state shown in FIG. 7 to the state along the Y direction shown in FIG. Ru. Further, the left and right element rows 32 that move relatively from the wide side portions 631B, 641B side to the narrow side portions 631A, 641A side between the inner side surfaces 631, 641 are held between the narrow side portions 631A, 641A in the Y direction. Therefore, the left and right element rows 32 are connected (engaged) with each other by being held by the pressing surface 421 and sandwiched by the inner surfaces 631 and 641.

The connected left and right element rows 32 exit from the rear side of the slider 1. As described above, the slider 1 connects the left and right element rows 32 by running in the +X direction.
