PROBLEM TO BE SOLVED: To provide an orthodontic apparatus providing a maximum correction effect without giving constraint to a body independent of differences in the physical structures of users. SOLUTION: This orthodontic apparatus for the hip joint internal rotation deformation is provided with a pair of knee holder parts 250 rotating with the knees with the knees held therewith, a rotation driving part reciprocatingly driving to normally/inversely rotate the knee holder parts 250 in the direction of externally/internally rotating the knees, and a memory storing the rotating conditions of the knee holder parts 250. This apparatus includes a control part controlling the rotating driving part according to the rotating conditions stored in the memory. In another embodiment, this orthodontic apparatus for the hip joint internal rotation deformation is provided with a pair of leg rests stably supporting the legs and installed to normally/inversely rotate in the direction where the legs externally/internally rotate, and a third resistance means resisting to the normal rotation of the leg rests.
