<P>PROBLEM TO BE SOLVED: To provide a connection mechanism of a hanging rod for a ceiling board increased in strength and having an easily engageable and disengageable elastic hook member. <P>SOLUTION: In the elastic hook member 8A, a base plate part 9 is joined to the vertical main plate part 2 of the hanging rod 1a for a ceiling board. A reinforcement rib 16 having a folded plate reinforcement part 17 extending along the vertical lateral direction of a folded plate part 13 and a fitting tongue piece reinforcement part 18 extending along the projecting direction of a fitting tongue piece part 15 is so formed in the folded plate part 13 and the fitting tongue piece part 15 formed on the extended plate part 12 extended from the base plate part 9 as to be recessed to the extended plate part 12 side. Consequently, the strengths of the folded plate part 13 and the fitting tongue piece part 15 are increased, the recessed fitting tongue piece reinforcement part 18 is formed in the sharp hooking part of a tool when the fitting tongue piece part 15 is pressed to the extended plate 12 side for engagement and disengagement, and the engagement and disengagement can be performed easily since the bending of only the fitting tongue piece part 15 to the extended plate part 12 side does not occur. <P>COPYRIGHT: (C)2009,JPO&INPIT |
