ABSTRACT OF THE DISCLOSURE A tilt adjustment mechanism for an object lens driving device (4) includes a base (13), a housing (3), a spherical supporting member (14) and adjustment screws (18a, 18b; 18c; 18d). The base (13) holds the object lens driving device (4). The housing (3) is provided with a supporting point (17) for supporting the base (13) and two adjustment points (20a, 20b; 20c; 20d). A straight line interconnecting the supporting point and one of the adjustment points is substantially at right angles with a straight line interconnecting the supporting point and the other of the adjustment points. The surface of the housing (3) facing to the base (13) is formed with a concave portion (17). The supporting member (14) is interposed between the base (13) and the housing (3) so as to be in point contact with the base and the housing. The screw hole (19a; 19c; 19d) is provided in one of the base and the housing. The holding portion (3c; 13d, 23a, 23b, 25a, 25b, 26a, 26b; 25c, 25d) for holding each of the adjustment screws meshing with this screw hole is provided to the other of the base and the housing.
