Abstract

PROBLEM TO BE SOLVED: To restrain dispersion of a backlash of gears. SOLUTION: A first gear (a driving gear) 1 is rotatably installed on a gear installing plate 4, and a second gear (a driven gear) 2 meshes with the first gear 1. The gear installing plate 4 is installed in a casing. A pin 6 protrusively arranged in the casing is arranged in the radial direction of the first gear 1 perpendicular to a straight line connecting the respective centers of the first and the second gears. An engaging hole 7 to engage with the pin 6 is formed in the installing plate 4, and a lever 8 is installed on the opposite side of the engaging hole 7 to the center of the first gear. The gear installing plate 4 is slightly rotated in the circumferential direction with the pin 6 as the center by pressing the lever 8 by a micrometer 9 installed in the casing, and a backlash of the gears is adjusted.
