(54)	Rotation operation part and electronic device

(57) The present invention provides a rotation operation part which is capable of absorbing shaft misalignment by a sufficient deformation force even when the shaft misalignment from a rotation type electronic part is generated in any direction. A rotation operation part formed by integrally molding an operation portion having a screw hole, a base portion, and a shaft portion which connects both the portions from elastic resin is manufactured, and the base portion is fixed to a rotation type electronic part. The shaft portion includes a spiral spring wound around a rotation shaft thereof, and shaft misalignment from the rotation type electronic part is absorbed by deformation of the spiral spring.
