A method for manufacturing washer includes steps of providing a wire material, deforming part of the wire material to be a ring shape, cutting off the part in the ring shape to obtain a ring-shaped wire material, and forging the ring-shaped wire material into a washer having a split defined by end surfaces at two opposite ends of the ring-shaped wire material.

A process of forming a turbine engine seal includes the steps of: providing a flat strip of material; roll forming the flat strip of material forming an asymmetric profile in the flat strip of material; coiling the formed asymmetric profile into an overlapping ring shape; cutting the circular shape to a predetermined length; and joining ends of the predetermined length forming the seal. The seal includes at least two peaks that are formed on opposing sides of a gap. The at least two peaks contact opposing sides of a U shaped profile at a zero radius. The asymmetric profile includes a circular shape and the ends are joined.

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.

A washer includes a first washer piece formed in a circular arc shape and formed with a first fitting portion that protrudes from one end in a circular arc direction; and a fourth washer piece formed with a second fitting portion that is recessed from one end in the circular arc direction and fitted with the first fitting portion. The first fitting portion and the second fitting portion are fitted in a state where approach and separation therebetween in the circular arc direction is controlled. One of the first fitting portion and the second fitting portion includes a crimped portion that is formed in a state where a side surface of the one of the fitting portions is pushed into a side surface of the other of the fitting portions, the one of the fitting portions being fixed to the other of the fitting portions by the crimped portion.
