Abstract

A jig body on an assemlbing jig is vertically aligned with the shaft upon which the boot is to be mounted and is movable forward and away from the shaft along an axial line thereof. A seat mounted on the leading end of the jig body receives an inner end face of the boot. A guide sleeve mounted on the jig body projectable forward of the seat is normally retained forcibly forward of the seat predetermined length approximately equal to the length of the bead and is shaped to be fitted over the shaft and into the bead of the boot. A guide shaft mounted in the guide sleeve is slidable axially rearward relative to the sleeve and is shaped to abut against and center the end face of the driving shaft. A push rod is inserted in the jig body for urging the guide shaft axially forwardly. The push rod is provided with a restricting portion for restricting the axially forward sliding stroke of the guide sleeve to a predetermined extent. A first cylinder urges the jig body forward axially. A second cylinder is mounted on the piston rod of the first cylinder and is arranged to reciprocate the push rod.
