ROLLER FOR IN-FURNACE CONVEYANCE

摘要

A roller (1) for in-furnace conveyance is provided with engagement sections (30) at each of which an engagement hole (11) of a barrel section (10) and an engagement shaft (24) of a shaft section (20) are engaged with each other, and the roller is formed as a single roller by welding the engagement sections (30). The engagement sections are each provided with: a first engagement section (31) at which the engagement hole (11) and the engagement shaft (24) are engaged with each other at a position separated from the position of the weld with a predetermined gap provided therebetween; and a second engagement section (32) at which the engagement hole (11) and the engagement shaft (24) are engaged with each other at a position adjacent to the position of the weld with a gap provided therebetween, the gap being greater than that of the first engagement section.
