(57) Abstract Constitution The damping steel sheet make bracket which was hung to beam 3The synthetic resin make ray of the pair which is locked to 4 and bracket 4ru be able to provide the Interpolation through-hole 15 for 5 and wire 2, curtain openThe time the runner itself of the synthetic resin make which this touches with those which are adjacent 1Roller 26 of the synthetic resin make which convolutes on 6 and carriage rail 5This it touches to carriage rail 5 and regulates lateral movement of bi runner itself 16The runner 6 which possesses the guide idler 34 of the ru synthetic resin makeIt possesses. Advantages At the time of curtain opening and closing operation while contacting mutually, phaseOpposite the part, contact with the wire the part and the curtain which are movedThe part which this touches at the time of open operation consists of all synthetic resin materialsFor the sake of the contact which is not the times when metal sound is generated, furthermore describesThe sound which is generated and by this connection transmits to beam 3 and resonatesThere is no ru thing. Therefore, silence at time of curtain opening and closing operationIt means that Characteristic is superior very.
