A vertical saw machine includes a column with upper and lower supports carrying a motor to drive a saw blade. A table is disposed between the upper and lower supports for supporting a workpiece thereon. The saw blade intersects the table with an included angle. The column is turnable between normal and inclined positions to vary the included angle. A frame post is mounted under the table to be positioned on the ground surface An arcuate key slot is formed in the frame post such that the motor projects through the key slot to be guided therealong so as to retainingly turn the column between the two positions -A worm gearing mechanism includes a worm wheel segment and a worm that are respectively mounted to the column and the frame post and that are operable to turn the column.
