Abstract
An oil level gauge having a simple structure so as to be readily assembled, an accidental disconnection of a handle from a rod being prevented, favorable contact between a rubber packing and an inner wall of a gauge insertion pipe being assured, and a reliable water-proof arrangement being obtained to prevent water from entering into an oil tank. The oil level gauge includes a rod including an oil level indicator at its lower end, a handle provided at an upper portion of the rod, and a rubber packing fitted on the rod in the vicinity of the handle; and these components are tightly assembled each other via a pressing force provided by the rubber packing which is being compressed.
