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 16 B is fitted onto a male shaft in a state of interference, and by causing the male shaft 16 A to slide back-and-forth a specified number of times in the axial direction with respect to the female shaft 16 B while applying, for example, a load in a direction that bends the male shaft 16 A with respect to the female shaft 16 B, friction heat is generated between side surfaces 411 of grooves 41 in the female shaft 16 B 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 16 A. 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 16 A to slide back-and-forth with respect to the female shaft 16 B in this state, the grooves 41 of the female shaft 16 B and the teeth 51 of the male shaft 16 A 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.

The present invention relates to a flywheel apparatus for energy storage and recovery including a flywheel system coupled to a flywheel drive system. The flywheel system includes a housing with a chamber in which a flywheel on a shaft rotates. The shaft is mounted on the housing via at least one damper which may allow but constrain and/or damp movement of the flywheel and shaft relative to the housing. The flywheel system has a flywheel lubrication system. The flywheel drive system may have a different type of fluid from the flywheel system. The two fluids may be kept separate by a sealing arrangement. Movement of the flywheel shaft relative to the housing is accommodated by a link member which allows the flywheel shaft to move relative to the housing. The link member also prevents the sealing arrangement from becoming damaged or becoming ineffective, and may also act as a mechanical fuse.

According to the present invention, a low surface-roughness part (114a) is formed at a first tapered part (114), and, as a result, the roughness of an opening-edge of a groove part (113a) of an internal spline part (113) that opens at the first tapered part (114) is reduced, and surface pressure applied by the opening edge to a tooth (123b) of an external spline part (123) can be reduced. As a result, the opening edge of the groove part (113a) of the internal spline part (113) can be kept from digging into the tooth (123b), and variation, between products, in the insertion load of a second shaft part (12) can be suppressed.
