摘要 |
A gas sensor includes a sensor element and a housing having an accommodation hole in which the sensor element is disposed. The housing has at an axial end thereof a cold crimped portion which cooperates with a shoulder portion of the accommodation hole to fixedly hold therebetween the sensor element. The cold crimped portion has an inward flange section, a hollow cylindrical section and a bent section between the inward flange section and the cylindrical section. The cold crimped portion is shaped so as to vary in thickness suddenly at or adjacent the bent section so that the cold crimped portion is assuredly bent at a predetermined position.
