Abstract

PURPOSE:To uniformize joining force of a carriage arm and a pivot shaft and to improve its assembling property in the disk device. CONSTITUTION:The carriage arm 8 is divided into two front and rear constitutive elements as a front carriage 8a and a rear carriage 8b, and they are fixed with screws to the side surface of the pivot shaft 7 to be integrated into one body. By this method, the pivot shaft 7 can be fixed to the carriage arm 8 without using an adhesive, and its fixing force can be managed to be constant. Then, because of no need of consideration of an adhesive in quantity and crowd- out, etc., the assembling property is hence improved.

That is, the pivot shaft is inserted into the integral carriage arm and fixed by adhesion, but in this method, since the pivot shaft is inserted after the adhesive is applied, the amount of the adhesive enclosed is
The distribution is uneven and the adhesive strength is not constant. This is because it is difficult to set the clearance of the insertion hole of the pivot shaft and the integrated carriage arm, and if the clearance is set too small, the adhesive applied when the pivot shaft is inserted falls. Further, if the clearance is large, the adhesive is anaerobic, so that the adhesive does not cure and the adhesive strength becomes insufficient. In addition, there is a problem that the assemblability is poor. Therefore, it is an object of the present invention to provide a disk device that makes the joining force between the carriage arm and the pivot shaft uniform and improves the assembling property.
