In this member connection structure, when the tenon portion 43 elastically contacts the groove bottom facing surface 33 of the female tenon groove portion 55 at a predetermined position, the convex portion 87 of the tenon portion 43 snaps into the concave portion of the groove bottom facing surface 33 of the female tenon groove portion 55 . fits. In other words, when the elastic connection of the tenon portion 43 is completed, the operator can perceive that the tenon portion 43 has been fitted into the female tenon groove portion 55 at the proper position by a sense of moderation. Further, the tenon portion 43 and the female tenon groove portion 55 are restricted from easily sliding in the mating releasing direction compared to a structure in which the convex portion 87 and the concave portion are not present. As a result, it is possible to confirm that the tenon portion 43 is locked at a predetermined position of the female tenon groove portion 55, and to hold the tenon portion 43 firmly connected.

Also, although illustration is omitted, in the member coupling structure according to the above-described embodiment and modification, a groove having a U-shaped cross section is formed in one member 11, and the edge (end edge) of the other member 13 is formed in this groove.
