PURPOSE:To enhance the positioning accuracy of a component part with respect to a shaft, by disposing a resilient member in a space defined between a groove or a semicircular recess formed in the outer peripheral part of the shaft and projection formed on the inner peripheral part of the component part. CONSTITUTION:A resilient member 4 is disposed in a space defined between a predetermined axial width groove 5 formed in the outer peripheral part of a shaft 2 and crossed by a semicircular cross-sectioned shape groove 21 which is formed in the outer peripheral part of the shaft 2, orthogonal to the groove 5, and a projection 6 formed in the inner peripheral part of a component part 3 and having therein a recess 61. With this arrangement the resilient member 4 is engaged with both recesses 21, 61 so that the relative displacement between the shaft 2 and th component part 3 is inhibited, and thereby the positioning accuracy of the component part 3 with respect to the shaft 2 may be enhanced. |
