Claims

[Scope of utility model registration request]

a float chamber that communicates with a storage tank that stores a liquid to be detected and into which the liquid to be detected is introduced; a float provided within the float chamber that floats due to the buoyancy of the liquid to be detected; and a rod member connected to the float. A first diaphragm chamber that is connected, a first diaphragm chamber that is divided into two chambers by the first diaphragm, a second diaphragm chamber that is divided into two chambers by the second diaphragm, and one of the second diaphragm chambers. a flexible cylindrical member that communicates and connects the chamber with one of the first diaphragm chambers; and a flexible cylindrical member that is interposed within the cylindrical member and has ends connected to the first diaphragm and the second diaphragm, respectively. A liquid level detection device for an internal combustion engine, comprising a linear member, a liquid level support member attached to the second diaphragm, and a pump that increases pressure within the cylindrical member.
