車構造。A ring-shaped boss portion formed on the back plate, comprising a blade wheel boss portion fixed to the main shaft of the turbomachine, a back plate attached to the blade wheel boss portion, and a blade attached to the back plate. The inner periphery of the ring-shaped boss of the back plate is supported by the outer periphery of the circumferential part of the blade wheel boss, and the ring-shaped boss of the back plate is expanded while rotating the blade wheel boss and the back plate together. In order to allow deformation in the radial direction, a radial pin attached to the circumferential portion of the blade wheel boss portion is inserted into a pin hole formed in the ring-shaped boss portion of the back plate. Features a turbomachinery blade wheel structure.
