PURPOSE:To prevent a relative shift of an outer layer body and an inner layer body and its deformation to be caused by vibration and oscillation, etc., with the lapse of time by forming a coupling by many recessed parts and projections in the longitudinal direction and the peripheral direction in a boundary part, in a double layer coupling rod-like body. CONSTITUTION:In the inside of a pipe-like outer layer body 2 made of aluminum, an inner layer body 3 made of steel is fitted into plural recessed parts 4 of the outer layer body 2 through many pin-like projections 5, 5... provided in one body on the outside peripheral surface in the peripheral direction and the axial direction of the inner layer body 3 and coupled mechanically as one body. In such a way, a double layer coupling rod-like body 1 has large resistance as a shift against oscillation and vibration in the axial direction and the peripheral direction in the course of operation, and the generation of shift and deformation, etc., can be prevented.
