ABSTRACT:
The diametrically larger end of a boot abutted on the open end of a joint unit on a vertical posture driving shaft is separated from the open end and held there while a liquid such as a grease is injected through the opening thus created. The end of the boot is then fitted over the outer periphery of said open end. A boot opening/closing device for doing so includes a vertically movable clamping member for clamping the boot at a portion adjacent the larger end, moving it away from the open end, holding it there during injection of the liquid by a movable nozzle and fitting it.
