PURPOSE:To reduce the number of harnesses and assure an installation space for a motor or the like, by jointly using a part of a rotational angular position detection harness laid in a piston rod, for an oil temperature sensor. CONSTITUTION:A rotational angular position detector 6 provided in a piston rod 10 and a signal conversion circuit 7 connected to a signal comparator circuit 3 are connected to each other through rotational angular position detection harnesses 40, 41, 42 so that a two-bit signal is transmitted. A harness 43 for an oil temperature sensor 31 and a harness 44 for an oil temperature compensation circuit 30 are connected to the common harness 41 and the signaling harness 40 so that oil temperature information from the oil temperature sensor 31 in the piston rod 10 is sent to the oil temperature compensation circuit 30 located outside the piston rod, through the utilization of the common harness 41 and the signaling harness 40. |
