Abstract

PURPOSE:To obtain a compact rotary head assembly which is excellent preventing the leakage of a lubricating fluid, and high in accuracy, by forming a fluid bearing lubricating part between a rotary sleeve and a center fixed shaft, and placing a magnetic fluid and a magnetic in an open end part of the open fixed cylinder side. CONSTITUTION:An example applied to a cylinder part of a VTR is shown in the figure. An upper cylinder 20, a rotary sleeve 21, an upper cylinder cover 22, a gasket 23 and a bolt 24 are shown in the figure, the upper cylinder 20 is fitted into the rotary sleeve 21 so as to be freely detachable, and is clamped with a bolt 35. A housing of the side where a fluid bearing is rotated is constituted of the cylinder 20, the sleeve 21 and the cylinder cover 22, in the inside. The gasket 23 is provided in order to prevent the leakage of a lubricating fluid. A magnetic seal part 46 consists of a permanent magnet 47, yokes 48, 49, a flange part 50, a rotary sleeve small diameter part 51 and a magnetic shielding plate 53, and leakage of lubricating oil from a lubricating oil tank 52 is prevented.
