The invention relates to a cone-shaped crusher including a frame having a cavity, a main shaft disposed eccentrically in the frame, and an eccentric drive making the main shaft perform a gyratory movement. The eccentric drive includes an upper eccentric shaft, a lower eccentric shaft, and an eccentric bearing. The upper eccentric shaft has an opening provided at its central portion to allow the lower end portion of the main shaft to pass through the opening, and an upper coupling part provided at its lower portion and fastened to the lower eccentric shaft. The lower eccentric shaft has a lower coupling part fastened to the upper eccentric shaft. The eccentric bearing accommodates the lower end portion of the main shaft and is disposed in a space defined by the upper eccentric shaft and the lower eccentric shaft.
