PURPOSE: To fix a stringer on a support leg without using bolts and nuts at the end section by providing a groove section on the head section of the support leg, and removably coupling the end section of the stringer with the groove section.
CONSTITUTION: A groove section 8, extending in the suspending direction of a stringer 15 and storing the end section of the stringer 15, is formed on the head section of a support leg 4. Irregularities coupled with each other when suspended are formed at the bottom section of the groove section 8 and the bottom section of the stringer 15, and irregularities 17, 18 coupled with each other at the time of suspension for closely sticking the bottom section of the stringer 15 to the bottom section of the groove section 8 are formed on the side face of the groove section 8 and the side face of the stringer 15. Both end sections of the stringer 15 are removably coupled with the groove sections 8 of adjacent support legs 4.
