The invention is a liquid filled type vibration isolating device () which includes a partition member () that partitions a liquid chamber () within a first attachment member () filled with a liquid into a first liquid chamber () and a second liquid chamber (), and in which a restricted passage (), which is configured to allow the first liquid chamber and the second liquid chamber to communicate with each other, is formed in the partition member. The restricted passage includes a first communication part () opening to the first liquid chamber, a second communication part opening to the second liquid chamber, and a main flow passage () that allows the first communication part and the second communication part to communicate with each other. At least one of the first communication part and the second communication part includes a plurality of pores () that penetrate a first barrier () facing the first liquid chamber or the second liquid chamber. At least one pore of the plurality of pores has a flow passage length of the pore that is 3 times or more the minimum value of the internal diameter of the pore.

Vibration isolating device

In order to be able to easily check the state of foreign matter contained in oil regardless of an installation location, a device main bodyhaving a housing chamberin which oil is stored, a plugattached to a bottom portion of the housing chamberin a state where an end surface of a shaft portionfaces upward, a spacer memberformed by a transparent member and arranged on the plugin such a manner that one end surfacefaces an inside of the housing chamber; and an imaging unitarranged on the plug, the imaging unitimaging the inside of the housing chambervia the spacer memberare provided.

Mechanical device

A strainer device includes a strainer element; a first lid member that covers an upper opening of the strainer element; a second lid member that covers a lower opening of the strainer element and has a fitting hole in a portion surrounded by the strainer element; a delivery pipe protruding upward inside a hydraulic oil tank in a state in which the delivery pipe is fitted into the fitting hole of the second lid member; and a check valve arranged at the first lid member. The check valve includes a valve main body having a valve passage whose one end opens to the internal space of the strainer element and whose other end opens to inside of the hydraulic oil tank; and a valve body which is arranged to be able to move in a vertical direction with respect to a valve seat provided in the valve passage.
