In a connection surface (3c) of each of two members (1a, 1b) to be fastened, a communication groove (6) opened on a surface and an engagement groove (7) communicating therewith, being wider than the communication groove (6), and provided with a connection surface (9) parallel to the connection surface (3c) are formed. A fastener (8) includes: two engaging pieces (11), which can be inserted into the engagement grooves (7) and are wider than the communication grooves (6) and are provided with fastening surfaces (15); and a connecting portion (14) therebetween, wherein the entirety of the fastener (8) can be inserted into the interior of one set of communication groove (6) and engagement groove (7), which are opposed to and communicate with each other, by thrusting the respective engaging pieces (11) and connecting portion (14) thereto. In the inserted state, fastening surfaces (15) of the respective engaging pieces (11) contact with engagement surfaces (9) of the engagement grooves (7), thereby being unable to be pulled out in a direction orthogonal to the connection surfaces (3c) of the two members (1a, 1b). That is, the two members (1a, 1b) have nothing protruding from a surface by virtue of the fastening assembly, and are in a firmly fastened state via the fastener (8). <IMAGE> <IMAGE> <IMAGE> |
