Abstract
Provided is an optical imaging probe that is able to obtain a stable observation image by a dynamic pressure bearing. An optical imaging probe for guiding rearward a light entering a front end includes: a rotation driving source adapted to drive and rotate a rotor; a tubular rotation shaft inserted and fixed over an axial direction in a rotation center side of the rotor; an optical fiber inserted in the tubular rotation shaft, the front end of which a light is able to enter; and a bearing member supporting the tubular rotation shaft in a rotatable manner, and the bearing member configures a dynamic pressure bearing adapted to generate a high lubricating oil film pressure locally at multiple positions in a circumference direction.
