| 1. An optical scanning apparatus comprising:
a laser light source which emits a laser beam;
a collimator lens which converts the laser beam emitted from the laser light source into a parallel beam;
a cylindrical holding member which holds the laser light source and the collimator lens; and
a frame member having a cylindrical hole into which the cylindrical holding member is inserted,
wherein the cylindrical holding member is fitted in an interference fitting manner in two positions which are away from each
other in an optical axial direction of the laser beam emitted from the laser light source in the cylindrical hole of the frame
member.
