Claims

[Claims for Utility Model Registration] (1) Separate upper and lower radial bearings are provided in a bearing holder fixed to the chassis, and the capstan shaft is rotatably supported by the upper and lower radial bearings. A capstan support mechanism for a tape player, characterized in that an upper radial bearing is fixed within a bearing holder, and a lower radial bearing is inserted into the bearing holder through a gap. Support mechanism. (2) In the part of the bearing holder where the lower radial bearing is inserted, there is a V that restricts the movement of the lower radial bearing due to the pressing force when the pinch roller presses against the capstan via the tape.
1. A capstan support mechanism for a tape player as set forth in Paragraph 1 of the utility model registration, in which a support surface in the shape of a letter is formed. (3) The capstan support mechanism for a tape player according to claim 1 or 2, wherein the bearing holder is formed by outsert molding of a resin onto the chassis.
