PURPOSE:To prevent a short supply of lubricating oil by providing the base of a housing with a lubricating oil receiver member closely adhered to the side of a ball-and-roller bearing in such a manner that the upper surface of the member is positioned near the inner peripheral surface of an outside wheel of the ball- and-roller bearing on the base side of the housing. CONSTITUTION:A lubricating oil receiver member 48 is mounted on the base of a housing 38 between ball-and-roller bearings 26, 28 disposed in the bearing housing 38, the upper surface 50 of the member being a little higher than the inner peripheral surfaces 56, 58 of outisde wheels 52, 54 of the ball-and-roller bearings 26, 28 on the housing 38 base side. Therefore, the moment lubricating oil dropped in a space between the ball-and-roller bearings 26, 28 from an oil path 44 collects in the upper surface 50 of the lubricating oil receiver member 48 the lubricating oil flows in between inside and outside wheels of the ball-and-roller bearings 26, 28 to function as lubricant. Thus, the bearings are not used before lubricating oil collects, which can prevent breakage of a bearing due to a short supply of lubricating oil. |
