記具のリフイール。 A locking device in which a press-fit hole and a locking hole with an inner diameter smaller than the press-fit hole are continuously provided from the front end on the inner surface of the tip opening of the resin tube, and a locking protrusion is provided on the outer surface of the rear end of the tip. A press-fitting shaft part whose outer diameter is set to have an appropriate press-fitting allowance with respect to the inner diameter of the press-fitting hole part of the shaft part and the tube is provided continuously from the rear end, and the tip is inserted into the locking hole part of the tube. The tip is joined to the tube by inserting the locking shaft so that the locking protrusion is pushed into the inner surface of the locking hole and press-fitting the press-fitting shaft of the chip into the press-fitting hole of the tube. A refill for writing instruments such as water-based ballpoint pens.
