摘要： Provided is a telescopic shaft having a coated section that reduces sliding resistance, with fluctuation of the sliding resistance according to sliding position of the telescopic shaft being reduced. A female shaft 16B is fitted onto a male shaft in a state of interference, and by causing the male shaft 16A to slide back-and-forth a specified number of times in the axial direction with respect to the female shaft 16B while applying, for example, a load in a direction that bends the male shaft 16A with respect to the female shaft 16B, friction heat is generated between side surfaces 411 of grooves 41 in the female shaft 16B and the coated section 61, which heats the coated section 61 and causes the coated section 61 to expand along the entire length in the axial direction of teeth 51 of the male shaft 16A. Therefore, the coated section 61 plastically deforms along the entire length in the axial direction of the teeth causing compressive strain to occur. By causing the male shaft 16A to slide back-and-forth with respect to the female shaft 16B in this state, the grooves 41 of the female shaft 16B and the teeth 51 of the male shaft 16A are uniformly in contact along the entire length in the axial direction, and thus sliding friction becomes constant along the entire length of the sliding range.

摘要： Construction is achieved capable of stably maintaining an inner column 43 on the inner diameter side of an outer column 42. The outer column 42, including a support section 46 is formed by using hydroforming to swell a hollow tube outward in the radial direction. A displacement bracket 34 is also integrally formed with the outer column 42 by tube swelling. Furthermore, raised sections 47a, 47b of the support section 46 are formed at three or more location in the circumferential direction on the inner circumferential surface of the outer column 42, and these raised sections 47a, 47b and the outer circumferential surface of the inner column 43 come in contact with each other at three or more locations in the circumferential direction.
