PROBLEM TO BE SOLVED: To simplify assembling process of a liquid bearing device that supports, in a non-contact manner, a rotating member with a film of lubricating oil formed in clearances on radial bearings. SOLUTION: A sealing member 4 comprises a base part 4a, and a leg part 4b integrally extending from the base part 4a downward in the axial direction. The base part 4a has an inner circumferential surface 4a1 forming a sealing space S1 between the surface 4a1 and the outer circumferential surface 2a of a shaft member 2. The leg part 4b has an inner circumferential surface 4b1 being larger than the inner circumferential surface 4a1 of the base part 4a in diameter and forming an oil retaining space S2 between the surface 4b1 and the outer circumferential surface 2a of the shaft member 2, and an abutting surface 4b2 abutting on the upper end surface 8c of a bearing sleeve 8. The bearing sleeve 8 is sandwiched between an abutting surface 7d1 at a stepped part 7d in the housing 7 and the abutting surface 4b2 of the leg part 4b of the seal member 4 in the axial direction, and is fixed in the housing 7.
