摘要:
A pressurized pen having excellent feeling of using it by allowing an easy knocking operation with small force is disclosed. The pressurizing member 18 includes an elastic cylindrical member 19. The elastic cylindrical member 19 has a large-diameter front cylinder portion of which a front end 20a in air-tight manner communicates directly with the rear opening portion 6b of an ink containing tube 6 and which forms the pressurizing chamber 22, and a small-diameter rear cylinder portion 21 which is coaxially connected to a rear end of the front cylinder portion 20 and in which the front end portion 17a of the pressing member 17 is pressed into a rear aperture 21a thereof. The inside of the ink containing tube 6 is pressurized by allowing the pressing member 17 to press the rear cylinder portion 21 into the front cylinder portion 20 and compressing the elastic cylindrical member 19 in the axial direction with the pressing chamber 22 air-tight.
