PROBLEM TO BE SOLVED: To provide a jaw crusher for reducing exchange cost of cheek plates by reusing by vertically reversing the cheek plates abraded in the lower discharge port vicinity.SOLUTION: When crushing work of a jaw crusher 1 advances, since abrasion in the lower discharge port 52-vicinity of cheek plates 6 and 6 becomes large by exceeding an allowable limit, the cheek plates 6 and 6 cannot be continuously used. The cheek plates 6 and 6 are suspended in suspension holes 611 and 611 by a crane via a wire, and the cheek plates 6 and 6 are removed from sidewalls 21 and 21, and the cheek plates 6 and 6 are lowered on a floor surface, and the wire is removed from the suspension holes 611. Next, the cheek plates 6 and 6 are suspended in a lower end side suspension hole 612 by the crane via the wire, and are installed on inner wall surfaces 211 and 211 of the sidewalls 21 and 21 by reversing the vertical direction of the cheek plates 6 and 6. The cheek plates 6 and 6 are guided by guide members 66 and 67, and are smoothly installed on the sidewalls 21 and 21.SELECTED DRAWING: Figure 2 【課題】下部排出口近傍が摩耗したチークプレートを上下反転して再利用できるようにしてチークプレートの交換費用を低減するようにしたジョークラッシャを提供する。【解決手段】ジョークラッシャ１の破砕作業が進むと、チークプレート６、６の下部排出口５２近傍の摩耗が許容限度を超えて大きくなるため、チークプレート６、６を使い続けることが出来なくなる。吊り孔６１１、６１１にワイヤーを通してクレーンでチークプレート６、６を吊り上げ、側壁２１、２１からチークプレート６、６を取り外し、床面にチークプレート６、６を降ろし、吊り孔６１１からワイヤーを外す。次に、下端側の吊り孔６１２にワイヤーを通してクレーンでチークプレート６、６を吊り上げ、チークプレート６、６の上下方向を反転して、側壁２１、２１の内壁面２１１、２１１に装着する。チークプレート６、６は、案内部材６６、６７に案内されて、側壁２１、２１に円滑に装着される。【選択図】図２
