ABSTRACT:
A rail-connecting jig for a linear guide provides: a jig body substantially U-shaped in section which is loosely mounted over guide rails, the jig body including a pair of right and left wings the inner side surfaces of which when the jig body is mounted on the guide rails, are confronted with two side surfaces of each guide rail in which rolling-element rolling grooves are formed; and at least two bar-shaped rollers which are engageable with the rolling-element rolling grooves of each guide rail. One of the two bar-shaped rollers is held on the inner side surface of one of the wings, while the other bar-shaped roller is arranged in the other wing of the jig body. A roller-pushing member is provided to move the other roller into and out of engagement with the guide rails. That is, a pair of guide rails can be aligned with each other by fitting the bar-shaped rollers in the rolling-element rolling grooves at the junction of the two guider rails. Thus, without use of an expensive measuring instrument, the guide rails can be accurately and efficiently connected to one another.
