[Scope of Claim for Utility Model Registration] A jig body, a support roller that is attached to the jig body and positions the pipe relatively rotatably, a push shaft that is attached to the jig body so that the amount of protrusion and retraction can be adjusted, and a push shaft. a tube cutting blade attached to the tip of the push shaft while facing the support roller; a support member attached to the push shaft so as to be slidable in the longitudinal direction of the push shaft; , a switching mechanism for switching between a state in which the support member is fixed to the push shaft and a state in which the support member is released from the fixation, and a grooving roller attached to the support member in a state opposite to the support roller; A protrusion is provided on one or both support rollers of the rollers at a location facing the tube cutting blade to narrow down the cutting point of the tube prior to cutting the tube, and the attachment position of the tube cutting blade relative to the tip of the push shaft is provided. and the mounting position of the grooving roller relative to the support member are spaced apart from each other by a predetermined distance in the axial direction of the pipe positioned on the pair of support rollers, and by sliding the support member back and forth, grooves are formed at the front and back of the cutting edge of the pipe cutting blade. A pipe jig characterized in that the tip of the application roller is configured to move.
