An opening/closing device of a home bar door is provided to prevent the breakage of the home bar door by reducing the impact generated in the lowering of the home bar door. An opening/closing device of a home bar door comprises a hinge member. The hinge member is comprised of a housing(20), a rotation shaft(25), a protrusion cover(29), a torsion spring(30), and a fixed shaft(35). One side of the housing is opened and closed with the cover(22). The housing has a joining plate(21) united in the home bar door. The rotation shaft comprises a connecting piece(25a) in a plurality of fixed lugs(26) at the outer circumference. The both ends of the torsion spring are fixed to the connecting piece of the rotation shaft and the housing. The torsion spring controls the turning of the home bar door. One end of the fixed shaft is inserted into a shaft joining groove(27) of the rotation shaft. The other side of the backup shaft is inserted into the side part of an opening part.
