<p>PURPOSE:To simplify the formation of a cylinder body by forming the latter from a rodlike member consisting of a cylindrical portion having an axial hole and a projecting portion 12 integrally incorporated with the periphery of the cylindrical portion with liquid connecting portions and discharging portions being provided in the projecting protion so as to be aligned together. CONSTITUTION:A cylinder body 3 is formed from a rod member 9 cut in a predetermined length and consisting of a cylindrical portion 11 having a hole 10 axially extended thereghrough, and a projecting protion 12 integrally incorporated with the periphery of the cylindrical portion and extending in the axial direction thereof. Then the projecting portion 12 including a head portion 13, a main portion 14 and a projection 15 is formed with a liquid connecting portions 5, 7, discharging portions 6, 8 and an auxiliary portion 75. Further, the cylinder body 3 is mounted with a reservoir 41 having a connecting portion 45 extending along but upward spaced from a main portion 43, a subportion 44 and a discharging portion 6. With this arrangement, the formation of the cylinder body is simplified and each portion of the cylinder body is also made easy to be treated.</p> |
