Patent ID: 7012502

Claim:
A sensor comprising: a thermistor element for generating an electric signal; a metal tube having one opened end and another closed end, into which said thermistor element is inserted; a plurality of electrode wires joined to the thermistor element so as to project outward over the opened end of the metal tube; a plurality of lead wires, which are covered by covering tubes with uncovered portions remaining and joined to the electrode wires, respectively, at the uncovered portions; a housing having an inner hollow space into which the electrode wires and the lead wires are accommodated together with a resin as a filler; an insulating case disposed inside the housing and provided with a partition section for separating the joined portions of the electrode wires and the lead wires from each other, the respective electrode wires from each other and the respective lead wires from each other; and an insulating material which is fed to fill inside the insulating case in a state that the opened end of the metal tube and the electrode wires extending therefrom are inserted in the insulating case and portions of the covered lead wires and uncovered portions thereof are also inserted therein, wherein said insulating case is provided with a rib member extending in a direction normal to a longitudinal resin flowing direction at a time of feeding the resin in the housing and abutting against an inner peripheral surface of the housing, and wherein said rib member is configured to allow said resin to flow longitudinally therepast.
