摘要：PROBLEM TO BE SOLVED: To provide an oil seal which can easily be removed and has no risk of bringing about complication of the end face shape of a component to be mounted and also a dimensional enlargement. SOLUTION: A oil seal 10 for a cross roller bearing includes a ring-shaped rubber lip 20 and a metal ring for reinforcement 30 to which the rubber lip is adhered fast, and the metal ring 30 is equipped with a ring-shaped reinforcing plate part 32 to which the rubber lip is adhered fast and a ring-shaped mounting plate part 31 which is continued to one end of the reinforcing plate part and is spreading outward in the radial direction, wherein the mounting plate part 31 is furnished with bolt holes 33 for mounting the oil seal on the applicable component 22 at certain intervals in the circumferential direction. The mounting plate part 31 of the oil seal 10 is secured to the component 22 using fastening bolt 5. Replacement of the oil seal 10 can be performed only through removing the bolt 5, which takes place simply, compared with the conventional arrangement in which oil seal is fitted in by pressing.
