To provide a yoke integrated shaft for enabling a slide effective length of a cross-shaped shaft to be greater.SOLUTION: A yoke integrated shaft includes a shaft one end of which points to a first direction and the other end of which points to a second direction, a cylindrical adapter fitted to the outside of one end of the shaft, and a yoke welded to an outside of the adapter, the shaft having a fitted part located at one end of the shaft and fitted to the adapter, and a shaft part extending from the fitted part in the second direction and being slidably supported by an outer tube, the shaft part having a resin coating layer covering an outer peripheral face, the yoke including an annular base part having a circular through-hole passing therethrough in the axial direction, and a pair of arms protruded from the base part in the first direction. The outer peripheral face of the adapter has a convex part protruded to the radial outside, and an inner peripheral face of the base part has a concave part engaging with the convex part in a peripheral direction.SELECTED DRAWING: Figure 4
