となっている。SUMMARY OF THE INVENTION In order to achieve this object, the present invention provides a hydraulic elevator having a tank for storing hydraulic oil of a hydraulic device of a hydraulic elevator and a lid which is detachably provided over an upper opening of the tank. In the hydraulic system of
A structure is provided above the oil level of the hydraulic oil in the front tank, where a wave preventing member having pores for suppressing the ripples of the hydraulic oil is provided.
