<p><P>PROBLEM TO BE SOLVED: To improve a workability of setting/resetting of a center core mechanism on connecting a subsidiary hose with a main hose. <P>SOLUTION: A center core mechanism 60 is composed of a center core 61 for a main passage and a core 65. A center core 68 for a subsidiary passage is projected on the outer peripheral surface of the center core 61 for the main passage. In order to set the center core mechanism 60, after moving a center core body 62 to an axial direction in the main passage 21a of the main hose 20, the center core body 62 is moved to a direction crossing to the axial direction so that the center core 68 for the subsidiary passage is passed through a branch port 25 and set in the subsidiary passage 31a. After that, a core 65 is inserted in the main passage 21a along the center core body 62 by a guide mechanism made up of a guide rail 62a and a guide groove 67a to be integrated with the center core body 62. In order to remove the center core mechanism 60, after pulling the core 65 from the main passage 21a, the center core body 62 is moved to a direction crossing to the axial direction. After that, the center core body 62 is moved to the axis direction so as to be removed from the subsidiary passage 31a and the main passage 21a. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
