<P>PROBLEM TO BE SOLVED: To allow heat of a heater to be effectively released to an engine head without suppressing or hindering longitudinal movement of the heater, in a glow plug with a combustion pressure detection sensor which has a sensor capable of detecting combustion pressure based on displacement produced as the heater is pushed from the front end side to the rear. <P>SOLUTION: In an annular air gap between an inner circumferential surface 54a of a front end annular part 54 in a housing and an outer circumferential surface 10b of the heater 10, a heat transfer member 20 is disposed which can make contact with both of the front end annular part 54 and the heater 10 simultaneously by being inclined and eccentric with respect to an axis line G of the heater or being moved in the longitudinal direction within a fixed range. Thereby, heat of the heater is transferred from the heat transfer member 20 to the front end annular part 54 of the housing and the engine head through a short path. <P>COPYRIGHT: (C)2013,JPO&INPIT |
