The protrusionson the opposite sides abut against or approach the side wall portionsof the groovewhen the coupling memberis placed in the groove, a spaceis formed on the side of the bottomof the groove, and a welding groovehaving a substantially V-shaped section is formed on the side remote from the bottomof the groove
