<P>PROBLEM TO BE SOLVED: To provide fittings including a deceleration device capable of surely decelerating a surface material in a simple structure while securing excellent convenience. <P>SOLUTION: The moving amount of a roller 32 to a device body 31 in the deceleration device 30 is changed corresponding to the opening/closing speed of a sash. While the roller 32 is not abutted to an abutment projection 319 in a normal opening/closing operation, the roller 32 is abutted to the abutment projection 319 to demonstrate a deceleration effect when the opening/closing speed is high. Thus, convenience is not damaged without generating large frictional resistance during normal use, and the sash is decelerated so that impact noise or the like is suppressed when the opening/closing operation is suddenly performed swiftly. <P>COPYRIGHT: (C)2012,JPO&INPIT |
