PURPOSE: A pinion shaft connection structure is provided to quickly and easily connect a pinion shaft of a steering gear box with a yoke of a steering middle shaft. CONSTITUTION: One end of a pinion shaft(10) is connected to a steering gear box, and a circular recessed groove(12) is formed on an outer circumferential face of the other end. A spline is formed in a length direction to transfer a rotational force by combining with a spline of the yoke(20). One end of the yoke(20) is combined to a steering middle shaft by a universal joint while the other end is formed with a combination hole(22) so the other end of the pinion shaft to be inserted. Plural installation holes(24) are interlocked with the combination holes and are formed on an outer circumferential face of the other end. A connection device(30) for combining the pinion shaft to the combination hole is inserted in the installation hole and is settled in the recessed groove(12). Thus, the pinion shaft is not displaced in a shaft direction.
