To provide a seat slewing gear by which a seat provided on a vehicle can be easily rotated.SOLUTION: A seat slewing gear 1 is used for a vehicle having a seat which includes a seat part. The seat slewing gear comprises a base plate 10 which can be fitted to the vehicle, a middle plate 30, and an upper plate 70. The middle plate 20 is so formed as to be rotatable with respect to the base plate 10 with a middle rotation axis Or_M, which is an axis extending a longitudinal direction of the vehicle, as an axis. The upper plate 70 can be fitted to the seat part, and is so formed as to be rotatable with respect to the middle plate 30 with an upper rotation axis Or_U, which is an axis extending in a plate thickness direction of the middle plate 30, as an axis. After the middle plate 30 is rotated, the upper plate 70 is rotated with the upper rotation axis Or_U as an axis so that when the upper plate is rotated together with the seat part, a locus when the seat is rotated passes inside the vehicle.SELECTED DRAWING: Figure 3

    【課題】車両に設けられた座席が簡易に回転できる座席回転装置を提供する。【解決手段】座席回転装置は、座部を含む座席を有する車両に用いられる。座席回転装置1は、車両に取付可能なベースプレート10、ミドルプレート30、アッパープレート70を備える。ミドルプレート20は、車両の左右方向に延びる軸であるミドル回転軸Or_Mを軸として、ベースプレート10に対して回転可能に形成されている。アッパープレート70は、座部に取付可能であり、ミドルプレート30の板厚方向に延びる軸であるアッパー回転軸Or_Uを軸として、ミドルプレート30に対して回転可能に形成されている。ミドルプレート30が回転後、アッパープレート70は、座部とともに回転したとき、座部が回転するときの軌跡が車両の内側を通るように、アッパー回転軸Or_Uを軸として回転する。【選択図】図3
