The shut-off valves are connected to an indoor unit of the air conditioner via refrigerant communication pipes. The bases extend upwards from a bottom frame of the outdoor unit (2). The fixing portion is continuous with the bases, and holds the shut-off valves in place such that a space exists below the shut-off valves. ## Claims ### Claim 1 A shut-off valve mounting structure for holding a shut-off valve connected to an indoor unit of an air conditioner via a refrigerant communication pipe in place in an outdoor unit of the air conditioner (1), the shut-off valve mounting structure comprising: a base configured to extend upwards from a bottom frame of the outdoor unit; and a fixing portion connected to the base, and configured to hold the shut-off valve in place, such that a space exists below the shut-off valve being held in place in the fixing portion. ### Claim 2 (depends on 1) The shut-off valve mounting structure according to claim 1, wherein the base includes two column shaped members, and the fixing portion connected to both of the two column shaped members. ### Claim 3 (depends on 1) The shut-off valve mounting structure according to claim 1, wherein the base and the fixing portion are connected together in a detachable and reattachable manner. ### Claim 4 (depends on 1) The shut-off valve mounting structure according to claim 1, wherein the base includes an engaging portion configured and arranged to engage at least a portion of an outline of a protrusion protruding inwardly from the bottom frame towards an inside of the outdoor unit. ### Claim 5 An outdoor unit of an air conditioner comprising: a casing including a bottom frame; a shut-off valve connected to an indoor unit via a refrigerant communication pipe; and a shut-off valve mounting structure holding the shut-off valve in place, the shut-off valve mounting structure including a base extending upwards from the bottom frame; and a fixing portion connected to the base with the shut-off valve being supported in place by the fixing portion with a space exists below the shut-off valve. ### Claim 6 (depends on 5) The outdoor unit according to claim 5, wherein the shut-off valve includes a gas-side shut-off valve and a liquid-side shut-off valve, and the gas-side shut-off valve and the liquid-side shut-off valve are offset in the depth direction so that the gas-side shut-off valve is positioned more to a front side than the liquid-side shut-off valve when viewed in plan. ### Claim 7 (depends on 5) The outdoor unit according to claim 5, wherein the base includes two column shaped members, and the fixing portion is connected to both of the two column shaped members. ### Claim 8 (depends on 5) The outdoor unit according to claim 5, wherein the base and the fixing portion are connected together in a detachable and reattachable manner. ### Claim 9 (depends on 5) The outdoor unit according to claim 5, wherein the base includes an engaging portion engaging at least a portion of an outline of a protrusion protruding inwardly from the bottom frame towards an inside of the outdoor unit. ### Claim 10 (depends on 7) The outdoor unit according to claim 7, wherein the base and the fixing portion are connected together in a detachable and reattachable manner. ### Claim 11 (depends on 7) The outdoor unit according to claim 7, wherein the base includes an engaging portion engaging at least a portion of an outline of a protrusion protruding inwardly from the bottom frame towards an inside of the outdoor unit. ### Claim 12 (depends on 9) The outdoor unit according to claim 9, wherein the base includes an engaging portion engaging at least a portion of an outline of a protrusion protruding inwardly from the bottom frame towards an inside of the outdoor unit. ### Claim 13 (depends on 2) The shut-off valve mounting structure according to claim 2, wherein the base and the fixing portion are connected together in a detachable and reattachable manner. ### Claim 14 (depends on 2) The shut-off valve mounting structure according to claim 2, wherein the base includes an engaging portion configured and arranged to engage at least a portion of an outline of a protrusion protruding inwardly from the bottom frame towards an inside of the outdoor unit. ### Claim 15 (depends on 3) The shut-off valve mounting structure according to claim 3, wherein the base includes an engaging portion configured and arranged to engage at least a portion of an outline of a protrusion protruding inwardly from the bottom frame towards an inside of the outdoor unit.
