In a leathered steering wheel, a leather layer is so arranged as to cover
a covered layer of a ring part, and the leather layer is formed by
stitching, along the circumferential direction of the ring part, a
plurality of leather materials to one another, and the end portions of
the leather material are structured with thin portions formed by thinning
the back sides of the end portions such that thickness around stitching
portions is lowered, wherein a length L1 from the stitching portion to
the end face of each leather material is set to be substantially equal to
or slightly smaller than a thickness t1 of a main portion of the leather
material, and the end face is brought into abutment to the covered layer.
