First, as shown in FIG. 8, while pressing the cover engaging part 63 of the cover member 60 against the base engaging part 51 of the base member 40 from above, the connecting part 25 of the second slider 20 is connected by the second cover part 62. cover.

Next, by pushing the cover member 60 further downward, the pair of left and right engaging claws 67 are guided by the pair of left and right guide surfaces 53 of the base engaging portion 51 and pushed outward in the Y direction. At this time, even if the engaging claw 67 is caught on the pair of left and right auxiliary guide surfaces 54, the engaging claw 67 is guided toward the guide surface 53 by the auxiliary guide surfaces 54.

Subsequently, by further pushing the cover member 60 downward, the pair of left and right engaging claws 67 cross over the pair of left and right guide surfaces 53, and the engaging surface 672 of the tip claw portion 671 becomes the engaging surface of the base engaging portion 51. 52, the engaging surface 672 engages with the engaging surface 52 in the Z direction while the engaging claw 67 is restored to its original state.

At this time, as described above, the engagement position between the cover engaging part 63 and the base engaging part 51 is determined by the position of the first slider 10 and the second slider 20 in the Z direction by the first holding part 43 and the second holding part 44. It will be at the same position as the presser foot position or below this position. Therefore, as described above, the slider structure 1 can be configured so that foreign objects are less likely to get caught in the cover engagement portion 63 than when the engagement position is located above the presser position, and the foreign objects can be caught. It is possible to reduce the possibility that the cover member 60 will come off from the base member 40.

Furthermore, when the cover member 60 and the base member 40 are engaged, the first cover portion 61 covers and presses a portion of the upper surface 153 and the pair of side surfaces 154 of the first connecting convex portion 151 of the first slider 10 . Therefore, even if an external force is applied to the connecting portion 15 of the first slider 10 by twisting the handle 18, the cover member 60 will not only cover a part of the upper surface 153 of the connecting portion 15 but also the pair of side surfaces 154. Since the first slider 10 and the cover member 60 are partially pressed down, mutual rocking of the first slider 10 and the cover member 60 can be suppressed, and the possibility that the cover member 60 will shift from a predetermined position with respect to the first slider 10 can be reduced.

[Modified example]
In the embodiment, the engagement position between the cover engaging part 63 and the base engaging part 51 is such that the first pressing part 43 and the second pressing part 44 are holding the upper plate part 12 of the first slider 10 and the second slider 20. It is located at the same position as the presser foot position in the pressing Z direction or at a lower position than that, but if the cover member 60 is configured to be difficult to come off from the base member 40 due to catching of foreign objects, the position is lower than the presser foot position. It may be in an upper position. Further, the above-mentioned engagement position may be arranged at the same position as the upper surface of the upper plate part 12 of the first slider 10 and the second slider 20 in the Z direction, or at a lower position than that. This makes it more difficult for foreign objects to get caught in the engagement portion, and makes it more difficult for the cover engagement portion 63 and the base engagement portion 51 to disengage from each other.

In the embodiment described above, the position of the engagement surface 52 in the Z direction (the above-mentioned engagement position) is located at the same position as the upper edge of the base side plate part 42 or at a lower position than that, but as described above, If the cover member 60 is configured to be difficult to come off from the base member 40 due to being caught by a foreign object, the cover member 60 may be located above the upper edge of the base side plate portion 42 .

In the embodiment described above, a pair of guide surfaces 53 that gradually widen from each other in the Y direction as they move downward, and a pair of auxiliary guide surfaces 54 that gradually spread from each other in the Y direction as they move toward the second slider 20 are engaged with the base. However, the base engaging portion 51 does not have the pair of guide surfaces 53 or the pair of auxiliary guide surfaces 54. The structure may be any structure as long as it can engage with the cover engaging portion 63, and therefore the structure of the pair of guide surfaces 53 and the pair of auxiliary guide surfaces 54 may be omitted. Furthermore, when the configuration of the pair of guide surfaces 53 and the like is omitted, the configuration of the guided surface 673 of the engaging claw 67 may be left in place or may be omitted.

In the embodiment described above, the connecting portion 25 is formed on the second slider, but this configuration may be omitted.

In the embodiment, the cover member 60 is configured to press at least a portion of the upper surface 153 and a portion of the pair of side surfaces 154 of the connecting portion 15 of the first slider 10, so that, for example, when the handle 18 is twisted, This reduces the possibility that the cover member 60 will shift from a predetermined position with respect to the first slider 10. By the way, when the main purpose is to reduce the possibility that the cover member 60 comes off from the base member 40 due to catching of foreign objects, etc., the engagement position between the cover engaging part 63 and the base engaging part 51 is set to the first position. It is only necessary that the presser part 43 and the second presser part 44 are arranged at the same position as the presser position in the Z direction where the upper plate part 12 of the first slider 10 and the second slider 20 is pressed, or at a lower position than that. The structure may be such that the member 60 does not press the top surface 153 or side surface 154 of the connecting portion 15 of the first slider 10.
