An attachment device for an aircraft landing guidance flashing light includes a pair of attachment arms 11; and a light emitting portion fixing plate 12. The light emitting portion fixing plate 12 detachably fixes an aircraft landing guidance flashing light. The light emitting portion fixing plate 12 is supported by the pair of attachment arms 11 such that an angle of the aircraft landing guidance flashing light is at a predetermined angle in a state where the aircraft landing guidance flashing light is fixed to the light emitting portion fixing plate. ## Claims ### Claim 1 An attachment device for an aircraft landing guidance flashing light, comprising: a pair of attachment arms; a light emitting portion fixing plate; a leg; and an angle checking unit comprising an angle display portion and a needle, wherein the light emitting portion fixing plate detachably fixes the aircraft landing guidance flashing light, wherein the light emitting portion fixing plate is supported by a first attachment arm of the pair of attachment arms and by a second attachment arm of the pair of attachment arms such that an angle of the aircraft landing guidance flashing light is at a predetermined angle in a state where the aircraft landing guidance flashing light is fixed to the light emitting portion fixing plate, wherein the attachment device further comprises an angle adjusting unit that adjusts the angle of the aircraft landing guidance flashing light by adjusting an angle of the light emitting portion fixing plate with respect to the pair of attachment arms, the angle adjusting unit comprising: a rotation shaft disposed on the pair of attachment arms; a movable shaft; and a hole for the movable shaft, wherein the attachment device further comprises a rotation shaft fixing unit that fixes the rotation shaft, wherein the hole is an arc-shaped hole centered on the rotation shaft, wherein the movable shaft is movable within the hole centering on the rotation shaft, wherein at least one of the movable shaft and the hole is disposed on the pair of attachment arms and the other is disposed on the light emitting portion fixing plate, wherein the attachment device is disposed on an installation surface through the leg, wherein the angle checking unit displays the angle of the light emitting portion fixing plate with respect to the pair of attachment arms, wherein the angle display portion is disposed at an upper end of the light emitting portion fixing plate on a first attachment arm side of the light emitting portion fixing plate, and wherein the needle is disposed on an upper end of the first attachment arm on a light emitting portion fixing plate side of the first attachment arm so as to face a center of the angle display portion. ### Claim 2 (depends on 1) An aircraft landing guidance flashing device, comprising: an aircraft landing guidance flashing light; and an attachment device for the aircraft landing guidance flashing light, wherein the aircraft landing guidance flashing light is fixed to a light emitting portion fixing plate of the attachment device, and the attachment device is the attachment device for an aircraft landing guidance flashing light according to claim 1. ### Claim 3 (depends on 2) The flashing device according to claim 2, wherein the aircraft landing guidance flashing light is an LED flashing light. ### Claim 4 (depends on 3) The flashing device according to claim 3, wherein the aircraft landing guidance flashing light comprises: a connection portion that connects a wiring outside the aircraft landing guidance flashing light and a wiring inside the aircraft landing guidance flashing light. ### Claim 5 (depends on 4) The flashing device according to claim 4, wherein the connection portion is a waterproof connector. ### Claim 6 (depends on 2) The flashing device according to claim 2, wherein the aircraft landing guidance flashing light comprises: a connection portion that connects a wiring outside the aircraft landing guidance flashing light and a wiring inside the aircraft landing guidance flashing light. ### Claim 7 (depends on 6) The flashing device according to claim 6, wherein the connection portion is a waterproof connector.
