PURPOSE:To obtain a desired indication accuracy characteristic, by arranging a drive plate to convert a displacement of a bimetal into an amount of rotation, a mobile pin provided on the drive plate and a driven plate having a plurality of notch grooves and pointers guided by the mobile pin. CONSTITUTION:A drive pin 3 is fastened at one end of a bimetal 2 and wound with a heat wire 4 as heat generating body. The other end of the bimetal 2 is fastened at a part 8a of a sensitivity adjusting plate 8 movable over the top face of a base point adjusting plate 7 to make the base point and the sensitivity adjustable. The drive pin 3 having mobile pins 31 and 32 is inserted through a drive groove 29 of a rotatable drive plate 27. Mobile pins 30 and 31 are made to engage notch grooves 25 and 26 of the driven plate 24 having a pointer 23 and the notch grooves 25 and 26 to drive the driven plat 24 through the notch grooves 25 and 26 with the mobile pins 30 and 31, thereby obtaining a desired indication characteristic. |
