Stop pin 10 (Fig. 1) cooperates with radially extending pins 12 and 14, fixed on swingable actuator 16, for limiting the swinging movement of actuator 16. Pin 10 is designed so that stopping the rotation of actuator 16 is cushioned. Actuator 16 is swingably mounted in plate 18, and may, for example, support magnetic heads that swing across a magnetic disk in a disk file assembly. Pin 10 is eccentrically mounted in sleeve 20 (Fig. 2), and sleeve 20 is provided with external screw threads 20A by means of which it is rotatably mounted in plate 18. Sleeve 20 is provided with a hexagonal slot 20B in its lower end. (Image Omitted) Pin 10 is mounted at its lower end in sleeve 20 so that there is an annular gap 22 between pin 10 and the inner surface of sleeve 20 for most of the length of pin 10, imparting flexibility to pin 10.
