オイルシール。 This is a pressure-resistant oil seal that is installed around a moving shaft to prevent oil leakage, and consists of an annular metal reinforcement and a seal body made of an elastic material that is integrally molded around the reinforcement. In a pressure-resistant oil seal in which the seal body has an annular lip portion that contacts the peripheral surface of the shaft, an annular stabilizing lip extends from the oil pressure acting side of the lip portion toward the inside of the oil acting space. This stabilizing lip extends to form an oil introduction gap with the circumferential surface of the shaft when oil pressure is not applied to the oil seal, and when oil pressure is applied to the oil seal. 1. A pressure-resistant oil seal characterized in that the stabilizing lip is deformed toward the shaft when the lip is bent, and the tip of the stabilizing lip is brought into contact with the circumferential surface of the shaft, thereby reducing deformation of the lip.
