PURPOSE:To firmly connection-support a ceiling substrate member by forming a slit for elastic deformation along the insertion direction of a ceiling backing member, and projectingly installing a bulged part for engagement towards the ceiling substrate member. CONSTITUTION:A connecting supporting metal fitting 20 is constituted of an engaging fixation part 21 engaged with the upper surface 4a of a runner 4, outside surface 4b, and the lower surface 4c, and a supporting connection part 25 having a U-figure-shaped section which is insertion-fixed into a space formed along the longitudinal direction of a connecting runner 6 connected in crossing at right angle with the runner 4. A slit 27 for elastic deformation is formed along the insertion direction of the runner 4 on the supporting connection part 25, and a bulged part 28 for engagement which projects toward the runner 4 is projectingly installed. Accordingly, the connecting support of the runner 4 is made firm, and the connecting runner 6 can be connected at an arbitrary position of the runner 4 in simple manner. |
