Abstract
The present invention is aimed at providing an improved heater for electronic thermostats which can increase clamping force between a wax case and the heater while allowing reduction in the number of components and cost reduction, thereby improving productivity and reducing manufacturing costs in manufacture of an electronic thermostat, while improving durability and operational reliability of an electronic thermostat. The present invention provides a heater for electronic thermostats including: a hollow tube open at one end thereof and closed at the other end thereof; a heating member disposed inside the tube and generating heat by electrical resistance; and lead wires supplying electric power to the heating member, wherein the tube is directly inserted into a fastening hole of a wax case through interference fitting such that the heater is mounted on the wax case.
