。[Claims for Utility Model Registration] (1) A fixed cylinder, a rotating shaft coaxially attached to the axial center of the fixed cylinder, a rotating body coaxially attached to the rotating shaft, and a rotating body coaxially attached to the rotating shaft. In a rotary head device for a videotape player, the rotary head device includes an upper drum that is coaxially supported and has a video head attached to an outer periphery of the lower end opposite to the upper end of the fixed cylinder. It has an annular bottomed groove surrounding the rotating shaft, and the bottomed groove is equipped with a large number of steel balls having a diameter smaller than the width of the groove so as to be rotatable and movable within the groove. Rotating head device. (2) In paragraph 1 of the claims for utility model registration,
A rotary head device characterized in that the steel ball is made of iron or stainless steel and has a diameter of approximately 1 mm and a mass of approximately 10 g. (3) In paragraph 1 of the claims for utility model registration,
The rotary head device is characterized in that the bottomed groove is constituted by a hollow member made of a thin plate member in an annular recess on the upper surface of the upper drum. (4) Scope of claims for utility model registration, paragraphs 1 and 2
2. The rotary head device according to claim 1, wherein the outer peripheral surface of the steel ball is coated with a synthetic resin having a low coefficient of friction and excellent wear resistance.
