An inner surface of an opposite end to a free edge of each annular flange is rounded so as to form a recess. Each annular flange of the outer sheet is received in the recess of one inner sheet. A pin is inserted through the annular flanges of a pair of inner sheets and a pair of outer sheets. Both ends of the pin are deformed so as to be received in the recesses of the outer sheets.
