PROBLEM TO BE SOLVED: To provide the snow blade of a snowplow capable of easily adjusting the edge holding force by an edge inverting mechanism. SOLUTION: A lock tool 11 is locked by a lock shaft 14 to prevent the inversion of an edge device 2 until the force of a prescribed value or above is applied to the lock shaft 14. When the force of the prescribed value or above is applied to the lock shaft 14, the lock shaft 14 is elastically deformed, then the locking of the lock tool 11 is released to invert the edge device 2. The fixed position of one support device 13b of support devices 13a, 13b supporting both end portions of the lock shaft 14 can be changed in the axial direction of the lock shaft 14 on a pedestal 1b, thereby the holding force of the edge device 2 can be easily changed.
