Claims

[Scope of utility model registration request]

A rotary support member and a fixed support member each having a rotating core and a stationary core constituting a rotary transformer attached thereto, and a pair of bearings provided on the fixed support member support a rotating shaft integrally provided on the rotating support member. In a rotary head drum for a magnetic recording/reproducing device which is supported to maintain a gap between a rotating side core and a stationary side core at a predetermined size, the inner ring of the bearing on the side closer to the rotational support member of the pair of bearings. and the rotational support member, is movable in the axial direction, and after setting the gap between the rotational side core and the stationary side core to a predetermined value, is used to abut against the inner ring of the bearing on the side closer to the rotational support member. A gap setting collar is provided that can be fixed while receiving a predetermined axial force from the outside, and is fixed to the rotating shaft and comes into contact with the inner ring of the other of the pair of bearings, and is fixed to the rotation support member. A rotary head drum for a magnetic recording/reproducing device, which is provided with a fixed collar that prevents movement in the axial direction.
