に作動油を補給することができる。 Inside the mounting tube 5, a first oil reservoir chamber 81 for storing hydraulic oil for the first hydraulic chamber 31 and a second hydraulic chamber 32 are formed by a partition wall 7 integral with the cylinder body 1.
The second oil reservoir chamber 8 2 is divided into two chambers, and both oil reservoir chambers 8 1 and 8 2 communicate with the oil tank 4 . Therefore, the oil tank 4 has both oil storage chambers 8 1 and 8 2
Hydraulic oil can be replenished.
油槽４には、その内部の貯留油面が規定レベル
以下に低下したとき、それを検知する油面センサ
９が設けられる。 The oil tank 4 is provided with an oil level sensor 9 that detects when the oil level stored therein drops below a specified level.
