Claims

[Scope of claim for utility model registration] (1) In a reservoir tank in which a float switch for detecting the oil level is installed vertically on the cap,
The float switch includes a level gauge that is vertically disposed on the cap and holds a reed switch therein, and a magnetic material that is loosely fitted to the level gauge so that its inner peripheral surface can move in the axial direction and that is magnetized on its inner surface. and a float to which the magnetic body is fixed, wherein the Curie temperature of the magnetic body is set to a high temperature range outside the appropriate range of oil in the reservoir tank. (2) In a reservoir tank with a float switch installed vertically on the cap to detect the oil level,
The float switch includes a level gauge that is vertically disposed on the cap and holds a reed switch therein, and a magnetic material that is loosely fitted to the level gauge so that its inner peripheral surface can move in the axial direction and that is magnetized on its inner surface. and a shape memory spring whose upper end is fixed to the upper part of the level gauge and whose shape is memorized so as to expand in a high temperature region outside the proper range of oil in the reservoir tank.
