<P>PROBLEM TO BE SOLVED: To provide a trigger type liquid ejector which suppresses the inclination of a piston to a cylinder when an operation lever is being pulled and prevents a liquid leaking from the inside of the cylinder to the outside. <P>SOLUTION: A cylinder 35 includes: an outer cylinder 37, opening toward the front, connected to a body 11; and a guide shaft 41, standing toward the front inside the outer cylinder 37 in a radial direction. A piston 33 includes: a cylindrical piston body 49 having a recessed part 49a opening toward backward into which the guide shaft 41 is inserted and having a front part connected to an operation lever 5; a sliding part 51 sliding on an outer peripheral face of the guide shaft 41; and a sealing part 53 liquidtightly sliding on the inner peripheral face of the outer cylinder 37. A communication path 55 communicating an inner chamber R<SB POS="POST">2</SB>and a cylinder liquid chamber R<SB POS="POST">1</SB>between the inner peripheral face of the sliding member 51 and the guide shaft 41 is formed, and the sliding part 51 is extended closer to the backside than to the seal part 53. <P>COPYRIGHT: (C)2012,JPO&INPIT |
