PROBLEM TO BE SOLVED: To provide a crane attachment structure which can inhibit deformation of a crane attachment portion associated with use of a crane by a simple structure without building a large reinforcement structure.SOLUTION: A crane attachment structure 1 includes a crane 2 which is provided at the vehicle inner side of an upper corner part at the rear side of a vehicle 10 in a manner that the crane 2 can rotate in an interior and exterior range of a cargo chamber 11 and can load and unload a cargo 100 to the interior and the exterior of the vehicle cabin 11 from a back door opening 12. The crane attachment structure 1 includes an attachment part 3, a reinforcement member 4, and a support member 5. The attachment part 3 includes an inner surface 30i to which the crane 2 is attached and an outer surface 30o opposite to the inner surface 30i. The reinforcement member 4 is joined to the outer surface 30o so as to form a predetermined space with the outer surface 30o of the attachment part 3. The support member 5 supports the attachment part 3 and the reinforcement member 4 while bridging therebetween in the space to inhibit deformation of the attachment part 3 associated with use of the crane 2.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】大型な補強構造を構築することなく、簡易な構成でクレーンの使用時に伴うクレーン取付箇所の変形を抑制できるクレーンの取付構造を提供する。【解決手段】クレーンの取付構造１は、車両１０後方の上部角部の車内側に荷室１１の内外の範囲内で回動自在に設けられて、バックドア開口１２から荷室１１の内外に荷物１００を積み下ろし可能なクレーン２を備える。クレーンの取付構造１は、取付部３と補強部材４と支持部材５と備える。取付部３は、クレーン２が取り付けられる内面３０ｉとその反対側の外面３０ｏとを備える。補強部材４は、取付部３の外面３０ｏとの間に所定の空間を形成するように外面３０ｏに接合される。支持部材５は、空間の内部で取付部３と補強部材４とを橋渡しして支持することで、クレーン２の使用に伴う取付部３の変形を抑制する。【選択図】図３
