<P>PROBLEM TO BE SOLVED: To provide a folded-plate roof receiving implement that can properly cope with the occurrence of thermal expansion or contraction in the longitudinal direction of a roof board material, in which the roof board material is long in the longitudinal direction as the flow direction of the folded-plate roof. <P>SOLUTION: A set of two spring units A with a winding thread 45, which are disposed in series, are provided in a unit housing part 1. The unit housing part 1 is provided on a base pedestal 6 in a slidable manner. In the spring units A, two wide-mainspring shaped constant load springs 2 are wound into an S shape while drums of the constant load springs 2 are wound by the winding thread 45 in which a predetermined torque is generated. A roof-surface fixing member 7, which is fixed to the unit housing part 1, is made movable in the flow direction of a folded-plate roof R against the elastic force of the constant load springs 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
