Abstract

PURPOSE:To prevent the generation of abnormal wear and seizure of a main bearing and the large diameter part of a main shaft even if the main shaft makes slant rotation by forming the outer circumference part of the large diameter part of a main shaft or the inner circumference part of a main bearing in a tapered shape in the shaft direction. CONSTITUTION:The outer circumference part of the large diameter part 6a of a main shaft 6 or the inner circumference part of a main bearing 39 is formed in a tapered shape in the shaft direction. Thus, a bearing clearance between the large diameter part 6a and the main bearing 39 is large on the upper end side and small on the lower end side. Therefore, as relative inclination between a bearing surface on the load side and the slanted large diameter part 6a becomes small and in parallel against the slant within a range of the bearing clearance between the main bearing 39 and a sub bearing 21 generated by rotation 21 load of the main shaft 6, capacitive resistance against the load can be improved.
