ABSTRACT:
A passage communication member is fitted in a first passage in a structural member, and has a head which is mounted in a slot in another structural member. The first passage in the structural member and a passage in the other structural member are held in communication with each other through a through hole that is defined in the passage communication member. Alternatively, a first engaging member is inserted in a recess defined in a structural member, and a second engaging member is retained in a slot in another structural member. When the first and second engaging members are coupled to each other by a fastening member, the structural members are firmly joined and fixed to each other.
