A machine tool capable of reducing the lateral width of the upper part thereof by reducing the lateral width of a bed ( 1 ) while machining through the same lateral moving distance of a spindle ( 10 ) as before, comprising longitudinal guide rails ( 2 ) installed on the bed ( 1 ), a slide ( 3 ) installed through the guide rails ( 2 ) movably in a longitudinal direction, a column ( 6 ) movable in vertical direction, wherein first cover plates ( 25 ) are fixed at the right and left sides of a vertical moving route for the spindle ( 10 ), side cover plates ( 26 ) are installed continuously with the outer end edges of the first cover plates ( 25 ) so as to be turnable rearward, a second cover plate ( 32 ) is installed at the front sides of the first cover plates ( 25 ) and the side cover plates ( 26 ) integrally with the slide ( 3 ) so as to cover the front side of the moving range of the column ( 6 ), and a shielded machining space (SK) is formed at the front of the second cover plate ( 32 ).
