Each of the side surface portions includes a first groove along which the first pin slides, and a second groove along which the second pin slides. The side surface portions support the support unit in such a manner that the support unit is rotatable around the first pin when the first pin is located at an end of the first groove. ## Claims ### Claim 1 A combiner lifting device comprising: a support including a first projection and a second projection, and supporting a combiner; and two side surface portions disposed on both sides of the combiner, respectively, each of the two side surface portions provided with a first groove along which the first projection slides, and a second groove along which the second projection slides, and supporting the support in such a manner that the support is rotatable around the first projection when the first projection is located at an end of the first groove, wherein the second groove includes a first groove area along which the second projection slides when the support rotates around the first projection located at the end of the first groove; and wherein the second projection is covered with a damper that fills a clearance between the second projection and the first groove area. ### Claim 2 (depends on 1) The combiner lifting device according to claim 1, wherein the second groove includes a second groove area in parallel with the first groove, and a width of the first groove area is smaller than a width of the second groove area. ### Claim 3 (depends on 2) The combiner lifting device according to claim 2, further comprising an electric motor that drives the support, wherein torque of the electric motor produced when the second projection is located in the first groove area is larger than torque of the electric motor produced when the second projection is located in the second groove area. ### Claim 4 (depends on 1) A head-up display device comprising: the combiner lifting device according to claim 1; a housing that houses the combiner lifting device; and a cover that covers an upper part of the housing. ### Claim 5 (depends on 4) The head-up display device according to claim 4, further comprising a cover opening/closing mechanism provided with a third groove along which the first projection slides, wherein the cover opening/closing mechanism is turnably disposed such that at least a part of the third groove extends in a direction different from an extension direction of the first groove, and wherein the cover is opened and closed in accordance with turn of the cover opening/closing mechanism. ### Claim 6 (depends on 5) The head-up display device according to claim 5, wherein the cover includes a first gear, and the cover opening/closing mechanism includes a second gear that engages with the first gear. ### Claim 7 (depends on 4) The head-up display device according to claim 4, wherein the second groove includes a second groove area in parallel with the first groove, and a width of the first groove area is smaller than a width of the second groove area. ### Claim 8 (depends on 7) The head-up display device according to claim 7, further comprising an electric motor that drives the support, wherein torque of the electric motor produced when the second projection is located in the first groove area is larger than torque of the electric motor produced when the second projection is located in the second groove area. ### Claim 9 A combiner lifting device according to comprising: a support including a first projection and a second projection, and supporting a combiner; and two side surface portions disposed on both sides of the combiner, respectively, each of the two side surface portions provided with a first groove along which the first projection slides, and a second groove along which the second projection slides, and supporting the support in such a manner that the support is rotatable around the first projection when the first projection is located at an end of the first groove, wherein: the second groove includes a first groove area along which the second projection slides when the support rotates around the first projection located at the end of the first groove, and each of the two side surface portions includes a rib that comes into contact with the second projection when the second projection slides along the first groove area. ### Claim 10 (depends on 9) The combiner lifting device according to claim 9, wherein: the second groove includes a second groove area in parallel with the first groove, and a width of the first groove area is smaller than a width of the second groove area. ### Claim 11 (depends on 10) The combiner lifting device according to claim 10, further comprising an electric motor that drives the support, wherein torque of the electric motor produced when the second projection is located in the first groove area is larger than torque of the electric motor produced when the second projection is located in the second groove area. ### Claim 12 A head-up display device comprising: a combiner lift; a housing that houses the combiner lift; a cover that covers an upper part of the housing; and a cover opening/closing mechanism provided with a third groove along which a first projection slides, wherein the combiner lift comprises: a support including the first projection and a second projection, and supporting a combiner; and two side surface portions disposed on both sides of the combiner, respectively, each of the two side surface portions provided with a first groove along which the first projection slides, and a second groove along which the second projection slides, and supporting the support in such a manner that the support is rotatable around the first projection when the first projection is located at an end of the first groove, the cover opening/closing mechanism is turnably disposed such that at least a part of the third groove extends in a direction different from an extension direction of the first groove, and the cover is opened and closed in accordance with turn of the cover opening/closing mechanism. ### Claim 13 (depends on 12) The head-up display device according to claim 12, wherein the second groove includes a first groove area and a second groove area, the second groove area is in parallel with the first groove, and a width of the first groove area is smaller than a width of the second groove area. ### Claim 14 (depends on 13) The head-up display device according to claim 13, further comprising an electric motor that drives the support, wherein torque of the electric motor produced when the second projection is located in the first groove area is larger than torque of the electric motor produced when the second projection is located in the second groove area.
