<P>PROBLEM TO BE SOLVED: To prevent an angle of a nozzle from becoming different more than a conventional angle when an external force is applied, in a cutting device having the nozzle for supplying a cutting liquid to an outer peripheral end of a cutting blade. <P>SOLUTION: In a constitution capable of varying the angle of the outer peripheral nozzle 811 integrally formed in a nozzle support 81 by rotating the nozzle support 81 rotatably fixed to a stay 735 of a front cover 73 by a bolt 821 and a nut 822, recesses and projections 738 and 814 are formed on an end surface 737 of the stay 735 and an end surface of the nozzle support 81 brought into a mutually pressure-contacting state in a fixing state, and the angle of the outer peripheral nozzle 811 is hardly displaced by holding the fixing state of the nozzle support 81 by the meshing of the recesses and projections 738 and 814 at fixing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
