A wood planing machine includes left and right mounting frames fixed uprightly on left and right mounting sides of a bed body. Left and right pairs of lifting rods are upright disposed rotatably on the bed body, and have lower ends extending into the bed body and connected to each other by a transmission belt. A working table is disposed on the bed body, and has four lugs connected operably with the working table such that rotation of the lifting rods results in movement of the working table relative to the bed body. Feed-in and take-out shaftd are journalled between the left and right mounting frames above the working table. A tool mounting shaft is disposed between the feed-in and take-out shafts and is journalled between the mounting frames. A motor for driving the tool mounting shaft is disposed movably in the bed body so as to permit tension adjustment of a transmissin belt trailed over an output shaft of the motor and the tool mounting shaft.
