Claims

[Scope of utility model registration request]

In the optical axis alignment mechanism of the optical module used to align the optical axis between the optical module holder or receptacle, the light emitting or light receiving element, and the support, the holder or receptacle is fixedly held and the optical axis can be adjusted in the X and Y directions perpendicular to the optical axis. A fiber fixing part that moves horizontally; a support holding part that is fixed to the upper part of the fiber fixing part and holds the support by a spring balance, and fixes the support by abutting it against the end face of the holder or receptacle in the optical axis direction; Or, it has a holder or receptacle that holds the light-receiving element fixedly and an element fixing part that moves up and down to adjust the focus in the direction of the optical axis relative to the support, and the light-emitting or light-receiving element is fitted with the support to adjust the focus. 1. An optical axis alignment mechanism for an optical module, characterized in that the support is slidable up and down and has a mechanism that moves horizontally to follow the position of a light emitting or light receiving element in order to align the optical axis with a holder or receptacle.
