PURPOSE:To obtain a stable revolution characteristic by arranging a movable plate and a static plate equipped with a bimetal into an oil tank for storing lubricating oil and setting the gap between the both plates to a prescribed value by utilizing the temperature characteristic of the bimetal. CONSTITUTION:Onto the outer peripheral edge part of a static plate 6, an annular bimetal 9 having the larger diameter than that of the static plate 6, and said static plate 6 is pressed onto a movable plate 3 side by an annular guide screw part 10 which is screwed onto the inside of an oil tank 1 through the annular bimetal 9. The static plate 6 is closely attached onto the movable plate 3 by heating or cooling the static plate 6 and the bimetal 9 before assembly, and the guide screw part 10 is revolution adjusted so that the gap A between the both plates becomes zero. When the normal temperature state is restored, the gap A between the both plates is automatically set to the designed dimension by the restoration action due to the temperature characteristic of the bimetal 9. |
