ABSTRACT:
In an optical disc apparatus, a lens holding body provided with an objective lens is mounted on a base body. The base body has a screw hole and is guided by a guide shaft. An adjusting screw screwed into the screw hole has a slidable portion formed by an annular groove portion and slidably fitting with a rail portion on a chassis side. Each screw thread of a male screw of the adjusting screw is divided into two half sections along the peripheral direction thereof in a manner that a screw thread as one side section and a screw thread as the other side section are slightly deviated positionally to each other in the axial line direction. The screw threads are made in contact with the two slanted surfaces of a female screw.
