<P>PROBLEM TO BE SOLVED: To prevent intrusion of water due to a respiratory phenomenon in an injector configured to take out a lead wire from the upper end opening of an injector body. <P>SOLUTION: An opening 31 where a lead wire 8 is taken out is sealed with a cap 4 formed of a metal or a resin, the lead wire 8 is inserted into an insertion hole 41 formed in the cap 4, and a space between the lead wire 8 and the insertion hole 41 is sealed with a sealing member 9. By raising the upper end face 91 of the sealing member 9 higher than the upper end face 42 of the cap 4, and by raising the upper face 42 of the cap 4 higher than the upper end face 32 of a body 1, water on the upper end face 91 of the sealing member 9 falls by gravity in the upper end face 42 side of the cap 4, subsequently falls in the upper end face 32 side of the upper body 3, and further falls in the outer peripheral face side of the upper body 3. Accordingly, water does not remain on each of the upper end faces 32, 42, 91, and the intrusion of water due to the respiratory phenomenon can be prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
