Abstract: A shoe providing support for the plantar arch of a foot is disclosed herein. The shoe includes a belt, guide members, and a dial unit. The belt includes a base end section fixed to an outsole at a position equivalent to a plantar arch of a foot of a user, and a leading end section covering a pair of blades. Both side edges of the belt can be separated from an upper of the shoe along a longitudinal direction of the shoe. The guide members are fixed to the leading end section of the belt, and engage with a wire, which engages the dial unit. The dial unit is used to wind the wire, thereby tightening or loosening the belt, and therefore the shoe to a wearer's foot, and is fixed to an outer side surface of the upper.

Abstract: An intermediate shaft comprising a shaft body including an axle portion and a portion having an approximately elliptic shape of cross section, both major and minor axes of the elliptical cross-section portion being longer than a diameter of the axle portion, and a ring-shaped member with a cross-sectional shape analogous to the elliptic cross-section portion. A method for assembling this shaft provides for a vibration damping member intervened between the housing member and elliptic cross-section portion for damping vibrations transmitted from the steering gear box. This method also ensures that the housing and the vibration damping members and the elliptic cross-section portion are fitted into an outer tubular envelope, and the ring-shaped member normally has a gap against the outer tubular envelope and transmits rotational torque from the outer tubular envelope to the elliptic cross-section portion when the ring-shaped member is contacted with the outer tubular envelope.
