    Abstract: PROBLEM TO BE SOLVED: To effectively prevent the leakage of grease caused by an inner pressure change of a bearing 120 and the intrusion of a foreign matter from the outside in a universal joint. SOLUTION: The sealing device for the universal joint includes a fixing part 13 fitted to an outer peripheral surface of a shaft 111 of a cross spider 110 in the universal joint, a seal lip 15 slidably brought into close contact with an outer ring 121 of a bearing 120 supporting the shaft 111 to be relatively rotatable, and a protecting ring 16 surrounding an outer peripheral side of the seal lip 15. Pressing parts 16a and 16b brought into close contact with the outer peripheral surface of the seal lip 15 and restricting an increase of a diameter and the displacement of the seal lip 15 are formed on the protecting ring 16, a grease holding part 17 is provided at a front side of an end of the seal lip 15, and a labyrinth seal 18 is provided outside the grease holding part 17.

    Abstract: Sealing devices (1) in which, when they are stacked in the axial direction, a grease (G) applied to sealing lips (12) and (13) of each sealing device (1) is prevented from coming into contact with and adhering to an attachment ring (11) of an adjacent sealing device (1). The sealing device (1) comprises an attachment ring (11) and, united therewith, sealing lips (12) and (13) made of a rubbery elastic material. It has a projection (17) made of a rubbery elastic material and located along the periphery of the attachment ring (11). When such sealing devices (1) are stacked in the axial direction, the projection (17) serves as a holding part to come into contact with the attachment ring (11) of the adjacent sealing device (1) located on the side which the sealing lips (12) and (13) face, whereby necessary gaps (´ 1 ) and (´ 2 ) are held between the grease (G) applied to the sealing lips (12) and (13) and that adjacent attachment ring (11).

    Abstract translation: 当密封装置（1）在轴向堆叠时，防止施加到密封装置（1）的密封唇（12）和（13）上的润滑脂（G）接触并粘附到 相邻的密封装置（1）的附接环（11）。 密封装置（1）包括一个连接环（11），并与之组合，由橡胶弹性材料制成的密封唇（12）和（13）。 它具有由橡胶弹性材料制成并沿着连接环（11）的周边设置的突起（17）。 当这种密封装置（1）在轴向上堆叠时，突起（17）用作保持部分，以与邻近的密封装置（1）的密封装置（1）的安装环（11）接触，密封装置 嘴唇（12）和（13）面对，由此在施加到密封唇缘（12）和（13）的润滑脂（G）和相邻的附接环（11）之间保持必要的间隙（'1）和（'2） 。
