The protector 82 is provided with a front section 82a and a rear section 82b which have an annular shape, and also with a connection section 86 from which a pair of wing sections 51, 52 of the sheath section 80 project and which connects the front section 82a and the rear section 82b while forming a space for enabling sliding of the sheath section 80. Position restricting mechanisms 81, 85 for positioning and fastening the sheath section 80 relative to the protector 82 at the piercing position and the stowed position are formed on the outer peripheral surface of the sheath section 80 and on the front side and rear side of the protector 82. <P>COPYRIGHT: (C)2010,JPO&INPIT |
