There is provided a method of manufacturing a washer capable of suppressing reduction in a sliding area, which includes: a preparing step of preparing a panel-shaped member N; a cutting step of cutting the panel-shaped member N with a laser L2 to thereby obtain a longitudinal member N1; and a forming step of obtaining an arc-shaped washer by using the longitudinal member N1. The panel-shaped member N has an equal width to a longitudinal width of the longitudinal member N1. The cutting step is a step of cutting the panel-shaped member N from one end to the other end in a width direction to thereby obtain the longitudinal member N1 and the forming step is a step of deforming the longitudinal member N1 into an arc shape so that cut faces of the longitudinal member N1 form an outer peripheral face and an inner peripheral face.

An insert bushing arrangement of a breaking hammer, a breaking hammer and a method of supporting a breaking tool of a breaking hammer is provided. The insert bushing arrangement includes a bearing support inside which an insert bushing is mountable. Between the bearing support and the insert bushing is one or more intermediate material layers for preventing jamming of the components.
