PROBLEM TO BE SOLVED: To provide a filler support fitting which contributes to improvement in field workability and productivity, and exerts good usability and handling ease. SOLUTION: The filler support fitting is formed of: a bearing portion 1 which crosses an insertion hole B1 penetrated in a skeleton B, and bears the fireproofing filler D filled in a gap between an internal surface of the insertion hole B1 and an insertion body C inserted into the same; leg portions 2 which extend from respective edges of the bearing portion 1 along a penetrating axial direction of the insertion hole B1; and a hook portion 3 which extends from an edge of at least one leg portion 2, and engages with an opening edge of the insertion hole B1. The bearing portion 1 has a plurality of plastically deformable fragile portions 5 formed therein at longitudinal intervals in a manner extending in a direction that intersects the longitudinal direction.
