駆動機構。[Scope of claim for utility model registration] A cutting center link 1 having an appropriate number of cutting edges and a pair of side links 2
A saw chain C, which is pivotally connected at , 2, is stretched endlessly on the guide bar 3, and the teeth of the chain sprocket 4 are engaged with the recess formed in the base of the cutting center link 1 to drive the saw chain C to rotate. In the chainsaw M constructed as described above, guide plates 5, 5 are attached to both sides of the chain sprocket 4, and the vicinity of the recess of the cutting center link 1 that meshes with the teeth of the chain sprocket 4 is connected to both guide plates 5, 5. A chain saw drive mechanism characterized in that a saw chain C is rotationally driven while being guided by a saw chain C. The shape of the trough between the teeth of the chain sprocket 4 corresponds to the bending angle of the base of the cutting center link 1 that meshes with the chain sprocket 4, and the shape of the trough forms a ridge that rises toward the center of the trough. The chain saw drive mechanism described in section. The outer periphery of the guide plate 5 has a polygonal shape so that its bending angle can be regulated by coming into contact with the lower surface of the side links 2, 2... of the saw chain C that meshes with the chain sprocket 4 and is fed. The chain saw drive mechanism according to item 1 or 2, which rotates in synchronization with the chain sprocket 4.
