A viewing window 2a is provided. For this reason, from the side opposite to the connection surface P22 of the second plate P2, the tip of the protrusion 11 in the state of being inserted into the engagement hole 21 of the female member 2 is viewed by a viewer, that is, a user or an operator. Therefore, it is possible to confirm whether or not the connection between the male member 1 and the female member 2 is confirmed.

  More specifically, as shown in FIG. 9, the protrusion 11 of the male member 1 (in FIG. 9, the male member 1 is colored) is engaged with the engaging hole 21 of the female member 2. In the state (before connection), the tip end of the protrusion 11 to be inserted (and a part of the flange portion 13) is the reduced diameter portion 211 of the engagement hole 21 from the side opposite to the connection surface P22 of the second plate member P2. The viewer can visually grasp a certain range in an unobstructed manner. On the other hand, in a state after the projection 11 of the male member is engaged with the engagement hole 21 of the female member 2 (after connection), the second plate member P2 is inserted into the engagement hole 21 from the opposite connection surface P22 side. Then, the observer can visually grasp substantially the entire large-diameter portion 112 of the protrusion 11 that has passed through the reduced-diameter portion 211 of the engagement hole 21. That is, the connection confirmation means J in the present embodiment is a region in which the protrusion 11 can be visually recognized from the anti-connection surface P22 side of the second plate member P2 in a state where the protrusion 11 and the engagement hole 21 are engaged with each other. However, it is comprised so that it may expand rather than the state before the protrusion 11 and the engagement hole 21 engage. And the observer who grasped | ascertained the difference of the visually recognizable area | region of the processus | protrusion 11 can confirm the pros and cons of engagement with the male member 1 and the female member 2. FIG. In addition, the spread of the visible region of the protrusion 11 can be confirmed three-dimensionally by moving the protrusion 11 from the back to the front.

  Thus, the viewer can confirm that the male member 1 and the female member 2 are engaged by grasping that the visible region of the protrusion 11 has expanded. In addition, if the colors of the male member 1 and the female member 2 are changed, it will be easier to visually recognize that the visible range changes before and after the projection 11 is engaged with the engagement hole 21.

Even if it appears, the male member 1 and the female member 2 can be more suitably attached to the first and second plate materials P1 and P2. For example, as shown in FIG. 7, if three types are prepared in which the front and rear dimensions of the outer fitting cylindrical portions 31 and 41 of the mounting members 3 and 4 are 3 mm, 6 mm, and 9 mm, the male member 1 and the female member 2 are prepared. In cooperation with the first and second plate materials P1 and P2 having a thickness dimension of 3 mm to 11 mm, it can be appropriately fixed.

  The present invention is not limited to the embodiment described in detail above.

  The connection object to which the fastener is attached does not have to be plate-shaped as a whole, and may not be capable of being developed into a plate shape. As long as at least the part where the female member is mounted on the connection object on the side where the female member is mounted is plate-shaped, the intended purpose can be achieved.

  The first and second connection objects may have any shape as long as they do not hinder the connection by the fastener, and are limited to the plastic hollow plate as shown in the present embodiment. It is not a thing. As the connection object, for example, cloth, metal, wood, resin, ceramic, glass, or various combinations of these may be considered. However, if the fastener is attached to the plastic hollow plate as shown in the present embodiment, the plastic hollow plate is allowed to be elastically deformed in a certain thickness direction. Can be attached in close contact with the plastic hollow plate.

  The cylindrical portion of the male member or the female member may not be cylindrical, but may be rectangular.

  It goes without saying that various shapes can be adopted for the protrusions.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
