A device is disposed through a base that is slidable along a rail, and flange shaped engagement edge portions extending along with side edges of the rail is engaged with a pair of opposed base side engaging means provided on the base, and a resin base side spur tooth portion with a desired width provided on the base is meshed with a resin rail side spur tooth portion with substantially the same width provided on a side surface portion of the rail so that the base is not made a position gap, whereby the base is fixed to the rail. To enable fixation of a device formed into an odd shape, the base is vertically divided into two parts so that an upper member can move on an axis with respect to a lower member. |
