Also, it is an object to provide a work holder for a through hole examination apparatus that can readily adjust the holder to be parallel at low costs. A work holder 18 is provided for a through hole examination apparatus, which retains a workpiece having through holes provided therein and transfers the same between a work replacement operation region and a through hole examination region. A roller movement device is mounted on the holder main body to enable a rolling movement thereof, and the roller movement device is made to be height-adjustable such that the parallel degree of the holder is adjustable.
