ABSTRACT:
A head drum assembly of a tape recorder in which an inner race and an outer race of an upper bearing are press-fitted onto a shaft and a rotary drum, respectively, thereby applying a preload. A resilient body, such as a compressed coil spring, is disposed between a lower bearing disposed between the rotary drum and the shaft and a stationary drum. The resilient body upwardly presses the inner race of the lower bearing, thereby applying a preload. Accordingly, the head drum assembly of the tape recorder provides enhanced assembling efficiency and reduced manufacturing costs.
