(Top board)
The top plate 5 is formed in a substantially rectangular shape in plan view. In the present embodiment, the top plate 5 is made of a resin such as polypropylene or polyvinyl chloride.

  The top plate 5 has a flat plate portion 5A formed in a substantially rectangular plate shape in plan view. The upper surface 5U of the flat plate portion 5A is a mounting surface on which an article can be mounted. In the upper surface 5U of the flat plate portion 5A, the end portion is formed so as to be gradually inclined upward as it goes outward.

Furthermore, the top plate 5 is bent from the lower end of the inclined wall portion 5B and extends downward, with the inclined wall portion 5B formed so as to be gradually inclined downward toward the outside from the end portion of the flat plate portion 5A. And a hanging wall portion 5C.
The flat plate portion 5A, the inclined wall portion 5B, and the hanging wall portion 5C constitute a top plate portion that covers the side surface 3B side from the upper surface 3A side of the seat member 3. Further, the inclined wall portion 5B and the hanging wall portion 5C constitute a side wall portion intersecting with the flat plate portion 5A.

  Furthermore, the top plate 5 has an engagement claw portion (top plate side engagement portion) 5D that protrudes inward (seat member 3 side) from the lower end of the hanging wall portion 5C. The engaging claw portion 5 </ b> D is formed over the entire periphery of the edge of the top plate 5.

At the boundary portion between the inclined wall portion 5B and the hanging wall portion 5C, a protruding portion 5T that protrudes toward the outside (side) of the planar view top plate 5 is provided.
The flat plate portion 5A, the inclined wall portion 5B, the hanging wall portion 5C, the engaging claw portion 5D, and the protruding portion 5T are integrally formed.

  In such a top plate 5, the engaging claw portion 5 </ b> D is engaged with the lower portion of the sewing portion 43 provided on the side portion of the seat portion 6. Thus, the top plate 5 is attached to the stool 100B. In this state, a space portion K is formed between the edge side of the flat plate portion 5A of the top plate 5, the inclined wall portion 5B and the hanging wall portion 5C, and the outer member 42 of the stool 100B.

When removing the top plate 5 from the stool 100B, for example, as shown in FIG. 4, the user puts his thumb on the edge of the flat plate portion 5A of the top plate 5 and the projection 5T of the top plate 5 with another finger. Is supported and lifted to raise the protrusion 5T. Then, the engaging claw portion 5D presses the outer surface of the stitching portion 43 inward. Thereby, the outer surface of the stitching portion 43 is elastically deformed so as to be recessed inward, and the engaging claw portion 5D moves upward so as to slide on the outer surface of the stitching portion 43. Then, the engagement between the engagement claw portion 5D and the stitching portion 43 is released, and the top plate 5 is removed from the stool 100B.
Here, the space K formed between the top plate 5 and the seat 6 functions as an absorption allowance for the seat 6 in which the space K is elastically deformed when the top 5 is removed from the stool 100B. Therefore, the seat portion 6 is elastically deformed so as to enter the space portion K, and the protruding amount to the outside of the stitching portion 43 is likely to be reduced, so that the engagement between the engagement claw portion 5D and the stitching portion 43 is easily released. .

  On the other hand, when attaching the top plate 5 to the stool 100B, the user places the flat plate portion 5A of the top plate 5 on the seat member 3 and pushes the edge side of the flat plate portion 5A downward. Accordingly, the side surface of the seat portion 6 is elastically deformed so as to be recessed inward, and the engaging claw portion 5D moves downward so as to slide on the outer surface of the stitching portion 43. The engaging claw portion 5D is engaged with the lower portion of the stitching portion 43. In this state, for example, when the table 100A is tilted, the engagement claw portion 5D and the stitching portion 43 are in contact with each other, so that the engagement claw portion 5D easily gets over the stitching portion 43 and the engagement is released. There is nothing to do. Thus, the top plate 5 is attached to the stool 100B.

In the table combined stool 100 configured as described above, the table 5 can be used as the stool 100B by removing the top plate 5 and sitting on the seat portion 6 in a state where it is removed. Moreover, the top plate 5 is provided on the upper part of the stool 100B and can be used as the table 100A. The seat 6 that is a part on which the user is seated when used as the stool 100B and the top board 5 that is the part on which the user places an article or the like when used as the table 100A are separate parts. . Therefore, while the seat part 6 has a function as a seating part of the stool 100B and the top plate 5 has a function such as a placement part of the table 100A, the functions as the stool 100B and the table 100A can be maintained. it can.
Since the seat member 3 has elasticity, the seating comfort is good. Moreover, since the top plate 5 has a flat plate portion 5A formed in a plate shape, an article can be stably placed. Further, in the upper surface 5U of the flat plate portion 5A, the end portion is formed so as to be gradually inclined upward as it goes outward. Therefore, when paper such as documents is placed on the top 5, it is easy to remove the paper, and when a drink placed on the top 5 is spilled, the liquid is not easily spilled outside the top.

  Further, since the engaging claw portion 5D is engaged with the lower portion of the stitching portion 43, the top plate 5 is not easily separated from the stool 100B.

  Further, since the engaging claw portion 5D is formed over the entire periphery of the edge of the top plate 5, the top plate 5 is engaged with the sewing portion 43 provided on the upper portion of the seat portion 6 over the entire periphery. Therefore, the top plate 5 is stably attached by the stool 100B. On the other hand, since the top plate 5 is removed from the stool 100B by releasing the engagement in a part of the periphery of the top plate 5, the top plate 5 can be easily removed.

  Moreover, when removing the top plate 5 from the stool 100B, in order to release the engagement between the engagement claw portion 5D and the stitching portion 43, the user puts his / her finger on the projection 5T of the top plate 5, When the protrusion 5T is lifted, the engagement between the engagement claw 5D and the stitching portion 43 is released. Therefore, the engagement between the engagement claw portion 5D and the stitching portion 43 can be easily released.

  Further, since the stitched portion 43 is a portion where the upper outer member portion 42A and the side outer member portion 42B are stitched together, it is not necessary to separately provide an engaging portion that engages with the engaging claw portion 5D.
