Abstract

An improved sealing structure of a glow plug for diesel engines is provided. The glow plug includes a heater assembly which consists of a heater casing, a heating element, and a power supply rod. The heater casing has disposed therein the heating element connecting with the power supply rod and also has formed on a periphery thereof a press fit wall press-fitted into a hollow housing in tight engagement with an inner peripheral wall of the hollow housing. An uneven surface is formed on one of the press fit wall of the heater casing and the inner peripheral wall of the hollow housing. The uneven surface is patterned with lines such as fine grooves or ridges oriented at an angle relative to a longitudinal center line of the glow plug for forming barriers when the press fit wall is forced into the hollow housing which establish airtight seals between the heater casing and the hollow housing.
