The present invention relates to a vehicle intermediate shaft, having a clearance reduction structure. The vehicle intermediate shaft includes: a tubular shaft which is opened at the front end thereof and formed with a hollow portion in the longitudinal direction; a solid shaft formed in the shape of a rod and inserted into the hollow portion; and a sliding member mounted between the inner surface of the tubular shaft and the outer surface of the solid shaft. The vehicle intermediate shaft further includes a preload section for pressing the outer surface of the tubular shaft. The preload section includes a pressing member for surrounding the outer surface of the tubular shaft, and a bushing for pressing and surrounding the outer surface of the pressing member. According to the present invention, it is possible to reduce clearances and lashes generated among the solid shaft, the slide member and the tubular shaft, and to prevent from creating noise. In addition, it is possible to improve the riding and handling performances of a vehicle and responsibility of a vehicle. Furthermore, production and quality control costs may be reduced by shortening process.
