Claims

[Scope of utility model registration request]

In a flywheel mounting mechanism for a tape recorder in which a flywheel is rotatably supported between a main board of the tape recorder and a sub-board disposed in parallel to the main board, an axis of the flywheel is attached to the sub-board. A through hole to be inserted is formed, a bearing having a substantially tongue-shaped elastic piece formed therein is attached to the sub-board so that its tip is located at a position corresponding to the through-hole of the sub-board, and the bearing is inserted into the through-hole. A flywheel mounting mechanism for a tape recorder, characterized in that the tip of the shaft through which the elastic piece is inserted is pressed in the longitudinal direction of the shaft by the tip of the elastic piece.
