ABSTRACT:
An exemplary optical disc drive apparatus includes a guide shaft configured to movably support a pickup head, and an elastically deformable member. The elastically deformable member includes a main body, and a cantilever slanting up from a middle part of a front edge of the main body. The cantilever is broad at a lower portion thereof and narrow at an upper portion thereof, and the cantilever is for resiliently pressing a corresponding end of the guide shaft. The elastically deformable member reduces a stress surface between the cantilever and the guide shaft, and lengthens the life span thereof.
