Abstract

An adjusting device is provided to adjust adjusting tension of a drive transmitting belt of a wood planing machine, and includes a protective cover and a position adjusting member. The machine has a machine body with a front wall, a drive shaft rotatably mounted on the machine body around a lower axis and extend outboard to the front wall, a motor with an output shaft that extends outboard to the front wall along an upper axis, and a drive transmitting belt trained on the output and drive shafts. The protective cover includes an upright abutting rear wall that extends beyond the output shaft in a transverse direction to the upper axis and that defines an opening to permit forward and outward extension of the output shaft and a transverse movement relative to the opening. The protective cover has left and right anchored points spaced from each other in a diametric direction relative to the opening. The adjusting member has an abutting front wall disposed transverse to the output shaft to abut against the abutting rear wall. The abutting front wall has an opening to permit forward and outward extension of the output shaft, and left and right anchoring points spaced from each other in a diametric direction relative the opening. A guide slot is formed through the left anchoring point in clockwise and counterclockwise directions relative to the opening.
