PROBLEM TO BE SOLVED: To provide a bearing device reducing also labor for maintenance at a lower cost despite a fact that a leak can be prevented of a lubricant of grease or the like. SOLUTION: A leak of a lubricant of grease or the like from inside a bearing device 10 can be effectively suppressed despite a constitution simple at a low cost without providing an O-ring, spacer, etc., by a leak preventing member 19 arranged to be fitted relating to a fixed shaft 1 between radial/thrust bearings 14, 16 to have a flange part 19b extended at least in a radial direction. Since no part of the O-ring or the like easily causing aged deterioration is contained, maintenance is also easy.
