Technical Examples
  1. A conventional crusher forms a hollow space between paralleled straight portions of a wedge body portion and inner side surfaces of expanding members at the time of performing an expanding operation and hence, an expanding force of tapered portions of the wedge is not transmitted to the whole expanding members whereby the force is dispersed and a large crushing force cannot be obtained.
