Abstract
The present application provides a thermostat and a manufacturing method thereof, which can easily assemble shell members constituting a shell and reduce manufacturing cost. The thermostat comprises a shell (1), a thermoelectric element (17) moving in an axial direction in response to the temperature of a cooling liquid, a valve body (15) opening and closing a communication part of a first flow passage (21) and a second flow passage (7) by moving away from and approaching a valve seat (20b) provided inside the shell in response to the movement of the thermoelectric element, and a force applying member (16) applying force to the valve body to the valve seat side. The shell comprises a first shell member (2) having a main body (20), the first flow passage and the second flow passage, and a second shell member (3) fastened to the first shell member by rotating in a circumferential direction of the first shell member and having a third flow passage (22).
