When wanting to move the cursor quickly As shown in FIG. 7, when the inward protruding piece portion of the housing 22d is pressed with a finger, the force directly acts on the shaft main body 22a,
As a result, the cursor moves faster. When it is desired to move the cursor slightly slowly, as shown in FIG. 8, by rotating the spherical body 22c with a finger, a little force is applied to the shaft main body 22a in a direction corresponding to the rotating direction. Therefore, the cursor can be moved slightly slowly.
