<P>PROBLEM TO BE SOLVED: To provide a liquid applicator vessel, the cost of which is reduced while maintaining the same impression from use as current products by decreasing the number of parts while maintaining the quality demanded from a rotary applicator vessel, and enabling assembly using a simple method. <P>SOLUTION: In the liquid applicator vessel, sealing sections 18a, 18a formed on the outer circumference of the front section of a piston 18 make sliding contact with the inner wall of an enclosed section 12 of a main shaft 10, and additionally a tubular portion 18b is formed having a female screw section 38 on the inner circumference and a pair of protrusions 36 configured from rib-shaped protrusions protruding radially outward from the outer circumference of the back section of the piston. A male screw section 40 which is threaded with the female screw section 38 of the tubular portion 18b is formed on the outer circumferential surface of the front section extending forward from the operating section 16a of a rotating body 16. The space of the enclosed section 12 is formed towards the front of the main shaft 10, and towards the back, grooves 42 which engage the protrusions 36 on the outer circumference of the tubular portion 18b are formed along the axial direction. <P>COPYRIGHT: (C)2011,JPO&INPIT |
