Claim:
A jaw crusher, comprising: a fixed jaw; a swing jaw that swings with respect to the fixed jaw; an outlet gap-adjusting mechanism that adjusts an outlet gap between the fixed jaw and the swing jaw by changing a position of the swing jaw with respect to the fixed jaw; a crusher frame that supports the fixed jaw and the swing jaw; a cheek plate; and a mounting member that mounts the cheek plate on an inner side of the crusher frame between the fixed jaw and the swing jaw, wherein the outlet gap-adjusting mechanism has an adjustment range and is configured to change the position of the swing jaw with respect to the fixed jaw and thereby adjust the outlet gap such that, in the adjustment range of the outlet gap-adjusting mechanism, the swing jaw covers the mounting member during operation of the jaw crusher, and the swing jaw does not cover the mounting member during exchange of the cheek plate.
