Abstract
A breather structure is provided with: a communication passage which communicates a cylinder oil chamber with the atmosphere; and a stem which is disposed in the communication passage. A stem receiving section is formed in the side of the connection passage on the side of the cylinder oil chamber, the stem receiving section allowing the stem to be disposed inside with a clearance which allows air to be discharged from the cylinder oil chamber while maintaining the hydraulic pressure within the cylinder oil chamber. An air discharge section opened to the atmosphere is formed on the side of the atmosphere in the connection passage. Also, a pit section which releases the clearance to the air discharge section and a restricting section which restricts the movement of the stem toward the air discharge section are respectively formed in the inner peripheral surface of the communication passage.
