| 1. A water temperature sensor for an air conditioner of automotive vehicles comprising:
a thermistor of which resistance varies depending on the temperature of cooling water of a heater core mounted inside an air-conditioning
case;
a housing body having a receiving portion, a lower housing and an upper housing,
the receiving portion formed in the lower housing and having a predetermined space for receiving and surrounding the thermistor,
the predetermined space being filled with thermosetting resin for fixing the thermistor,
the lower housing having a heat-transferring portion formed on a lower end side thereof, and
the upper housing being curved from an upper end side of the lower housing in one direction and having a connector formed
on an end portion thereof; and
terminal sections coupled to end portions of lead wires separately connected to the thermistor inside the housing body and
connected to the connector side,
wherein the lower housing extended in a substantially perpendicular direction to the heater core pipes is fixed to a heat-shielding
cover surrounding heater core pipes which the cooling water is flowing through, and are exposed to the outside of the air-conditioning
case to allow the heat-transferring portion to come into contact with the heater core pipes, and the upper housing extends
in substantially parallel plane with the heater core pipes.
