PURPOSE:To position simply and accurately a thermistor for a main body of a sensor and to improve assembling workability, by fitting or holding by pressing interposingly heat sensitive resistor such as the thermistor etc. and bringing elastically a pair of electrically conductive terminal pieces into contact with each positive and negative electrode part of the heat sensitive resistor when the resistor is fitted or held by pressing interposingly. CONSTITUTION:A tip end part of an element holding member 16 is branched nearly in U-shape to form a pair of flexible holding tongue pieces 16a, 16b facing each other and said tongue pieces 16, 16b are provided with element fitting holes 16C extending to an axis direction. After inserting a thermistor 17 between the tongue pieces 16a, 16b bending to the outsides with each other, the thermistor 17 is press-held interposingly by fitting with the fitting holes 16c and is fixed to prevent slip by a slip preventing step part 16d formed at the tip end of each tongue piece 16a, 16b. On the other hand, a contact part 18 formed at the inner end part of a terminal piece is brought into contact elastically with each positive and negative electrode 17a, 17b of the thermistor 17 and each positive and negative electrode of the thermistor 17 is conducted electrically out of a protective case 14 through a plug terminal part 19. |
