Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a bearing device with a seal member whose come-off is prevented without the need for machining a boss member and a bush and which is easily fitted through the boss member. SOLUTION: On an outer peripheral face 19A1 of a cylindrical portion 19A of a dust seal 19, three come-off preventing protrusions 20 are provided for preventing the axial come-off of the dust seal 19 from a seal fitting hole 12B of an arm boss 12. Thus, the come-off preventing protrusions 20 are integrally formed as part of the dust seal 19 without the need for cutting work for the arm boss 12 and the bush 14. The come-off preventing protrusions 20 are easily provided on the dust seal 19. The come-off preventing protrusions 20 are elastically deformed when fitted through the seal fitting hole 12B of the arm boss 12, and so the dust seal 19 is easily fitted through the seal fitting hole 12B with general press-in work.
