Abstract:
A rotation-preventive device for preventing rotation during relative sliding movement by making engagement between a boss section which is formed with a hole and a spline shaft section which is inserted into said hole and which is formed with spline grooves, said rotation-preventive device comprising:a first spine shaft member and a second spline shaft member which are provided coaxially with each other and which are formed by dividing said spline shaft section in a direction substantially perpendicular to an axis thereof; and a clearance-adjusting mechanism for adjusting a clearance in a circumferential direction between an inner wall surface of said boss section and an outer wall surface of said spline shaft section by rotating and displacing said first spline shaft member and said second splint shaft member in mutually opposite directions about a center of rotation of said axis, wherein said spline shaft is slidably disposed in said hole of the boss section after said first spline shaft and said second spline shaft have been rotated and displaced for setting said clearance.
