PURPOSE: To compensate the defect in the axial, radial or angular alignment by using an elastically deformable element for attaching a rigid casing which stores a shaft to a cover of a coder. CONSTITUTION: One end of the synthetic resin bellows 5 is mounted on an outer bearing 6 of a rigid casing 4 through an annular portion 5', and the other end is mounted on an inner bearing 7 of a cover 2 of a coder through an annular portion 5". Accordingly an element of a sensor can be mounted through the bellows 5 only by totally mounting the element on the outside of the cover 2, and then inserting the same into the cover 2, which makes the adjustment in mounting easy, and the defect in the axial, radial and angular alignment can be compensated. |
