ABSTRACT:
The drive unit is improved in precision while the number of its manufacturing steps is a minimum. The drive unit reduces its manufacturing cost, and comprises a base plate 1 assuming a predetermined shape in cross-section so as to form a pair of frame portions 2 in its opposite sides. The plate 1 is made of metal, formed by using an extrusion process, and provided with: a concave portion 4 with a central hole 3a through which a motor M is mounted on the plate 1; and, a mounting hole 3c through which a swing arm is mounted on the plate 1. The motor M has its spindle 5 mounted in the central hole 3a of the plate 1 in an insertion manner. The swing arm 6 has its base portion supported by a pivot 8 through a pair of ball bearings 7. The pivot 8 is mounted on the plate 1 through the mounting hole 3c in an insertion manner.
