Abstract
When crimping suspensions to carriage arms using a metal ball by applying ultrasonic vibration to a crimping tool, the suspensions can be crimped to the carriage arms without causing deformation to the suspensions and the like. A method of assembling a carriage assembly aligns attachment holes provided in front ends of carriage arms and crimping portions provided on suspensions to set the suspensions on the carriage arms and then presses a ball through crimping holes provided in the crimping portions while applying ultrasonic vibration to the crimping tool to crimp the suspensions to the carriage arms. When doing so, a ball, such as a ball whose surface has been subjected to a dimpling process, for which a load that acts on the ball when the ball passes through the crimping holes is low compared to a spherical ball is used to crimp the suspensions to the carriage arms.
