<P>PROBLEM TO BE SOLVED: To provide a cutting device capable of reliably suppressing deterioration in molding accuracy of grooves even with a constitution for holding a spindle of a cutting blade at one side end in the cutting device for forming a groove in the predetermined length on a groove formation surface. <P>SOLUTION: The cutting device includes: a rail body 10 installed in a groove formation direction; and a groove formation part 12 for forming the groove on the groove formation surface by being guided on a rail body 10. The groove formation part 12 includes: the cutting blade 62 for forming the groove by rotation-driving around the spindle; a driving motor 61 for giving the cutting blade 62 a rotation drive force; and a guided body, in which the driving motor part 61 is installed, which is guided in the groove formation direction along the rail body 10. The driving motor part 61 is fixed to the guided body so that the drive shaft goes along the groove formation direction. The cutting blade 62 is arranged in parallel to the groove formation surface, whose spindle is orthogonal to the drive shaft. The groove formation part 12 includes a spindle holding member for holding the spindle. The spindle holding member is collaterally arranged in the cutting blade 62, whose one end side is outwardly fit to the spindle and the other end side is fixed to the guided body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
