MOUNTING STRUCTURE OF GLOW PLUG, GLOW PLUG WITH BLOCKING MEMBER, AND BLOCKING MEMBER FOR GLOW PLUG

摘要

PROBLEM TO BE SOLVED: To provide a mounting structure of a glow plug that can prevent invasion of a liquid and a solid in an inner part of an annular groove and between female screw and male screw parts, and to provide a glow plug with a blocking member and a blocking member for the glow plug.

SOLUTION: A wall surface which constitutes a glow plug attachment hole 81 includes an annular tapered surface which is adjacent to a rear end side of a female screw 83 and whose diameter is expanded as going toward the rear end side in an axial direction and which forms an annular groove between the annular tapered surface and an outer peripheral surface of the glow plug 20. A blocking member 50 having an insertion hole 51, in which the glow plug 20 is inserted, blocks and seals the annular groove 87 in a position on a tip end side in the axial direction from a tool engagement part 25 of the glow plug 20.
