Abstract
A vehicular propeller shaft through which a rotary motion of a drive power source is transmitted to drive wheels and which includes a first tubular member and a second tubular member. The first tubular member has a large-diameter cylindrical section, a small-diameter cylindrical section having a smaller outside diameter than the large-diameter cylindrical section, and a tapered cylindrical section formed between one end of the large-diameter cylindrical section and the small-diameter cylindrical section. The large-diameter cylindrical section, the small-diameter cylindrical section and the tapered cylindrical section are formed integrally with each other. The second tubular member is coaxially joined to the first tubular member and formed of a material having a higher degree of strength than the first tubular member.
