Abstract

PROBLEM TO BE SOLVED: To prevent the inadvertent closing of the valve body of a solenoid valve so as to prevent the occurrence of an ignition failure when ignition is performed by press-rotating an operation knob. SOLUTION: A pin 99 is pressed to a step part 59. Thus, the pressing force of a coil spring is countered even when a hand pressing an operation knob is slackened slightly, the inadvertent moving of an operation shaft 85 in an A direction together with the pin 99 is prevented and the releasing of the pressing of a center rod to a pulling-in and out shaft is prevented. Thus, the shaft is made conductive by the detection of a temperature exceeding a specified level by a temperature sensor and the pulled-ion state is surely maintained until the shaft is held. Accordingly, the inadvertent closing of the valve body is prevented and the occurrence of an ignition failure is surely prevented.

Therefore, when the center rod 39 separates from the inlet / outlet shaft 19 of the solenoid valve 15, the vibration of the center rod 39 is absorbed by the pressing plate 287, and the inlet / outlet shaft 1
It is possible to prevent a shock from being applied to 9. Therefore, it is prevented that the input / output shaft 19 moves in the direction A away from the attraction by the magnet, the valve body 21 is seated on the valve seat 25, the supply port 8 is closed, and the burner combustion is inadvertently stopped. can do. Since the pressing plate 287 is made of a thin plate having elasticity, even if there is a slight variation in the length dimension of the center rod 39, the moving shaft 19, etc., the variation in this dimension is absorbed by the elastic deformation of the pressing plate 287. Therefore, the accuracy control of the center rod 39 and the like is eased.
