PROBLEM TO BE SOLVED: To provide a design for a blade center edge mounting site reconsidering a design standard for a blade center edge for a snow removing general-purpose plough, proper to the periodic renewal of an edge and aiming at sure clamping because a blade body is prevented from an impulse and an abrasion on the basis of severe natural conditions such as snow, soil and sand or the like in the edge. SOLUTION: Both clamping site designs of a blade center and a center edge are not related, a pro-bolt can be used by forming a blade center clamping hole in a round shape and a center edge clamping hole in a square shape, and only one of the blade center side may be clamped with a bolt by forming a square-shaped clamping hole adapted to the bolt, thus enabling the sure clamping. The shape of the blade center may be formed in a round hole having a conventional shape as it is, and can be applied to all of conventional blade center mounting snow removing general-purpose ploughs and special mounting auxiliary equipment is not required. Maintenance inspection and renewal can be facilitated, the clamping of the blade center and the center edge can be improved remarkably and the efficiency of a routine periodic inspection operation can be improved.
