- This is done by converting the race of the thrust bearing to one of a different size; the drive shaft is sometimes moved axially by about 1 mm on the basis of such an adjustment. However, even though the drive shaft moves in this way, the bottom wall surface of the counterbore hole facing the end surface of the drive shaft is formed in an immovable manner, so the distance between these opposing surfaces inevitably varies. That is, if the distance becomes too large, a gap will be created between the thrust race and the end surface of the drive shaft, causing play, and if the distance becomes too narrow, the sliding UJ surface between the thrust race and the end surface of the drive shaft will be The pressure exceeds the permissible limit and causes a seizure phenomenon.

位置は安定的に確保される。[Effects of the Invention] As described in detail above, the present invention supports a drive shaft end on which a thrust load is applied by a thrust race that is applied with a required biasing pressure by adjusting a displaceable race holder. Therefore, the top clearance of the piston can be easily set within the required range without compromising the machining accuracy of each component, and the surface pressure between the drive shaft end and the thrust race can be maintained at a positive surface pressure. Therefore, defects such as backlash and seizure can be skillfully eliminated. In addition, since the thrust race is prevented from rotating in a chain manner from the drive shaft, the adjustment position of the race presser can be stably maintained.
