PIVOT SHAFT STRUCTURE AND RECORDING MEDIUM DRIVE DEVICE

摘要

A pivot shaft structure where a holder body (42A), engagement piece (42B1), and a pivot member (44) are pivotally installed on a flat plate-like installation member (40A) through a pivot shaft (70) is constructed from a pair of first support piece sections (71) and a pair of second support piece sections (72). The pair of first support piece sections (71) is arranged near the pivot center of the holder body (42A), engagement piece (42B1), and pivot member (44), and a through-hole is provided in each of the pair. The pair of second support piece sections (72) is arranged on the flat plate-like installation member (40A) so as to face the first support piece sections (71), and a though-hole is provided in each of the pair. The pivot shaft (70) has a support shaft section (73) penetrating the through-holes of the first support piece sections (71) and those of the second support piece sections (72) and has a come-off prevention shaft section (74) integrally formed in a bending manner at one end of the support shaft section (73) to prevent the support shaft section (73) from coming off.
