を特徴とする工作機械の工具交換装置。 A vertical spindle having a tool device hole at the lower end, a drive bevel gear mounted on the lower end of the vertical spindle so as to rotate together, and a drive bevel gear that is engaged with the vertical spindle so as to be able to slide vertically relative to each other along the spindle head of the vertical spindle. a slider which is coupled to the main shaft head via a spring so as to be able to move vertically; and a slider which is rotatably attached to a diagonal shaft projecting diagonally from the slider and meshes with a drive bevel gear of the main shaft. a tool magazine equipped with a driven bevel gear that can be driven; and a stopper for stopping a slider that allows only the spindle head to move vertically relative to the slider when the spindle head reaches a certain height in the vertical direction. When exchanging tools, indexing rotation of the tool magazine is caused by rotation of the main shaft, and the driven bevel gear on the tool magazine side has a number of teeth that is an integral multiple of the number of tools stored in the tool magazine. and is formed as a bevel gear having an inclination corresponding to the inclination angle of the oblique shaft. By rotationally positioning the drive and driven bevel gears in a certain position, the drive and driven bevel gears are smoothly and reliably engaged, and then the drive bevel gear on the main shaft side is connected to a rotation angle position detector and an NC device coupled to the main shaft. The tool is indexed by rotationally positioning the tool at a desired rotational angle position, and after indexing the desired tool, the desired tool in the tool magazine is mounted on the lower end of the spindle as the spindle head moves downward. A tool changing device for a machine tool, which is characterized by:
