An optical pickup angle adjusting mechanism of a beam angle adjusting structure consists of an external screw member and an internal screw part, while the external screw member is formed by integrating a flange engaging part engaging with a chassis to hold the edge of the chassis with two flanges, an external screw portion and a cylindrical press-fit part located between the flange engaging part and the external screw portion and the internal screw part includes a nut fixed to a pickup support part and a press-fit hole formed in the pickup support part coaxially with the nut for receiving the press-fit part in a close contact manner. Thus, a disk drive and a beam angle adjusting structure preventing adjusting screws from jolts can be obtained without increasing the number of components.
