The cover is reinforced by forming straight ribs, ring ribs, connection ribs, or hexagonal ribs having a honeycomb structure. The straight ribs, rings ribs, connection ribs, or hexagonal ribs are formed on the inner side or the outer side of a body of the cover on a side of an inverter. ## Claims ### Claim 1 An electric compressor comprising: a compressor housing including a driving unit and a compression unit for compressing a coolant; an inverter disposed at a side of the compressor housing; and a cover disposed at a side of the inverter, wherein the cover includes: a body; a side wall extending inwardly from the body and formed along an edge of the body; a plurality of fastening holes formed through the body to fasten the cover to the compressor housing; and a plurality of straight ribs formed on the an inner side or the an outer side of the body and extending toward the a center of the inner side or the outer side of the body from the fastening holes. ### Claim 2 (depends on 1) The electric compressor of claim 1, wherein the cover further includes a plurality of ring ribs formed on the inner side or the outer side of the body and connected to a portion of the straight ribs close to the fastening holes to surround the fastening holes. ### Claim 3 (depends on 1) The electric compressor of claim 1, wherein the cover further includes connection ribs connected to a portion of the straight ribs and formed in a circular shape around the center of the inner side or the outer side of the body. ### Claim 4 (depends on 3) The electric compressor of claim 3, wherein the connection ribs are coaxially formed with predetermined intervals around the center of the inner side or the outer side of the body. ### Claim 5 (depends on 1) The electric compressor of claim 1, wherein the straight ribs each further includes a first flange extending at both sides of a free end of each of the straight ribs. ### Claim 6 (depends on 5) The electric compressor of claim 5, wherein the straight ribs each further includes a second flange extending at both sides of a portion of each of the straight ribs. ### Claim 7 (depends on 1) The electric compressor of claim 1, wherein the cover further includes connection ribs formed on the inner side or the outer side of the body, and wherein the straight ribs, a plurality of ring ribs, and the connection ribs protrude inwardly on the inner side of the body or protrude outwardly on the outer side of the body. ### Claim 8 (depends on 7) The electric compressor of claim 7, further comprising an insulating member disposed on the inner side of the body. ### Claim 9 (depends on 8) The electric compressor of claim 8, wherein the straight ribs, the ring ribs, and the connection ribs are formed symmetrically to each other with respect to a horizontal center line of the body on the inner side or the outer side of the body. ### Claim 10 (depends on 9) The electric compressor of claim 9, wherein the straight ribs, the ring ribs, and the connection ribs are formed symmetrically to each other with respect to a vertical center line of the body on the inner side or the outer side of the body. ### Claim 11 An electric compressor comprising: a compressor housing including a driving unit and a compression unit for compressing a coolant; an inverter disposed at a side of the compressor housing; and a cover disposed at a side of the inverter, wherein the cover includes: a body; a side wall extending inwardly from the body and formed along the an edge of the body; a plurality of fastening holes formed through the body to fasten the cover to the compressor housing; and a plurality of hexagonal ribs formed on an inner side or the an outer side of the body. ### Claim 12 (depends on 11) The electric compressor of claim 11, wherein the cover further includes a plurality of ring ribs formed on the inner side or the outer side of the body and connected to a portion of the hexagonal ribs close to the fastening holes to surround the fastening holes. ### Claim 13 (depends on 12) The electric compressor of claim 12, wherein the hexagonal ribs and the ring ribs protrude inwardly on the inner side of the body or protrude outwardly on the outer side of the body. ### Claim 14 (depends on 13) The electric compressor of claim 13, further comprising an insulating member disposed on the inner side of the body.
