摘要： PROBLEM TO BE SOLVED: To suppress the deformation of a lip tip under a high pressure by minutely separating the tip angle part of a rubber lip tip arranged closer to a fluid housing chamber over a seal element and slid on a rotating shaft from a rotating shaft in a non-pressurized state, and bringing it into contact with the rotating shaft in a pressurized state. SOLUTION: In the non-pressurized state of a fluid housing chamber 33, the tip angle part 14 of a lip tip 13b in a rubber lip 13 is retained in a linear contact state or minutely separated state with no fastening margin to the circumferential surface of a rotating shaft 32. In the pressurized state of the fluid housing chamber 33, a self-sealing force F1 to the circumferential surface of the rotating shaft 32 acts on the tip angle part 14 since the pressure P of a high-pressure fluid acts on the lip part 13, and the tip angle part 14 makes contact with the rotating shaft 32. On the other hand, since no straining force by the rubber elasticity of the lip 13 is generated to the circumferential surface of the rotating shaft 32, the force acting on the rotating shaft 32 of the lip tip 13b is reduced by the portion of the straining force. Accordingly, the contact surface pressure of the lip tip 13b can be reduced to reduce the wear.

摘要： PROBLEM TO BE SOLVED: To realize the shortening of the axial dimension by forming a shallow annular recessed part along the pressure receiving side of the circumferential edge of a piston body to provide a thin wall part on the circumferential edge, forming the thin wall part into cover form, and fixing a seal lip thereto. SOLUTION: In the circumferential edge part 2 of a piston body 1, an annular recessed part 12 having a small dimension ΔT is formed along the pressure receiving side (pressure chamber 5 side), and a thin wall part 13 is provided on the circumferential edge part 2. The axial dimension A1 on the circumferential side of a piston 4 itself is reduced by ΔT, and the dimension B1 from the deep end surface 8b to the low pressure end side closer to the circumference of the piston body 1 is also reduced by ΔT. The axial dimension A1 of the piston 4 itself can be reduced, although the reduction is only the dimension ΔT of zero point several mm to about 3 mm, without loosing the strength, elastic repelling force, flexibility and sealing property of a seal lip 3 or while keeping the wall thickness T0 (thickness dimension) of the sheet metal piston body 1 as it is.

摘要： PURPOSE:To provide a rotary shaft seal which is designed to reliably prevent leakage of fluid during the rest and rotation of a rotary shaft and have excellent durability. CONSTITUTION:A seal lip part 10 making contact with the outer peripheral surface 4 of a rotary shaft 3 is provided with a first seal element 7 of a rubber resilient substance finished in a state that it is left molded. The first seal element 7 is disposed on the fluid containing chamber R side. A second seal element 9 formed of synthetic resin is in an annular plate-form manner in a free state. When the second seal element is inserted in the rotary shaft 3, the inner peripheral edge side is curved toward the fluid containing chamber R side to form a seal lip part 16 making contact with the outer peripheral surface 4 of the rotary shaft 3. A cut groove H is formed in the rotary shaft contact surface 17 of the seal lip part 16. The second seal element 9 is disposed on the low pressure side in a state to be brought into adhesion to the first seal element 7.
