PURPOSE:To prevent a control valve body from tilting and rocking, by making the tip end of an element case provided with a temperature sensor part contact with the whole circumference of a peripheral part of the control valve body. CONSTITUTION:An element case 18 having a temperature sensor body 19 and operating a control valve body 23 is made contact with the control valve body 23 via an annular contact surface. With this constitution, the control valve body 23 advances or retreats to or from the axial direction without being rocked following a movement in the element case 18. Therefore, valve opening to each of valve seats 28a and 29 is in no case varied at all, so that a cycling phenomenon in time of temperature setting is preventable from occurring. |
