In the figure, reference numeral 1 denotes a tooth plate body in the form of a square plate. On the front surface of the tooth plate body 1, a fractured surface 2 consisting of a large number of vertically extending ridges 2a having an arcuate cross section is formed, and on the back surface. A recess 3 is formed to improve alignment with a mounting surface of a frame or a swing jaw (both not shown). Engagement slopes 4 and 5 are formed on the upper and lower surfaces of the tooth plate main body 1 to engage with an engagement protrusion of a swing jaw or the like.

しかし、このジヨークラツシヤ用歯板において
