CUTTING BLADE FIXING MECHANISM

Japanese Patent JP2023054964

A

To fix a hub-less type cutting blade to a blade mount without using a fixing nut.SOLUTION: A cutting blade fixing mechanism is used to fix a hub-less type cutting blade to a spindle and has: a blade mount having a cylindrical boss part, and a receiving flange part protruding from a base end part of the boss part to the radial outer side of the boss part and including an annular first contact surface, the blade mount fixed to the spindle; and an annular fixing flange part which has annular rear and front surfaces and may sandwich the cutting blade with the receiving flange part. The blade mount further includes fixing members which protrude to the radial outer side of the boss part from an outer periphery side surface of the boss part, press the fixing flange part from the front surface side to the rear surface side, and sandwich the cutting blade between the receiving flange part and the fixing flange part to fix the cutting blade to the blade mount when the cutting blade is fixed to the blade mount with the fixing flange part.SELECTED DRAWING: Figure 3
