Abstract:
A hydraulic device of the present invention includes: a cylinder body (S) including a cylinder ( 1 ) and a rod ( 2 ) that moves retractably inside the cylinder ( 1 ); and a pump unit ( 30 ) that is formed with an oil passage ( 31 ) and discharges, at an intermediate position in the oil passage ( 31 ), liquid into the cylinder ( 1 ) through driving of a motor (M). The cylinder body (S) is connected to the pump unit ( 30 ) via an extension ( 40 ) having an oil passage ( 41 ) that provides communication between the oil passage ( 31 ) of the pump unit ( 30 ) and an interior of the cylinder ( 1 ).

Claim (Index 6):
The hydraulic device according to  claim 1 , further comprising:\n an outer cylinder accommodating the cylinder; a tank formed between the cylinder and the outer cylinder, the tank accommodating liquid; a piston passage provided in the piston, the piston passage being configured to allow only passage of the liquid from the contraction-side chamber to the expansion-side chamber; and a valve case closing one end of the cylinder, the valve case having an inlet passage that is configured to allow only passage of the liquid from the tank to the contraction-side chamber, wherein the oil passage of the oil passage member provides communication between the expansion-side chamber and the tank via the oil passage of the extension, and a variable relief valve that is possible of valve opening pressure change is provided at an intermediate position in the oil passage of the oil passage member.
