Claim:
1. An optical imaging probe for guiding rearward a light entering a front end, comprising: 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, a front end of which a light is able to enter; and a bearing member supporting the tubular rotation shaft in a rotatable manner, wherein the bearing member includes a dynamic pressure bearing adapted to generate a high lubricating oil film pressure locally at multiple positions in a circumference direction, wherein the rotation driving source has the rotor, which is arranged in a substantially cylindrical shape, and a coil provided in a substantially cylindrical manner and configured to cover a periphery of the rotor, wherein the optical fiber is provided in a non-rotatable manner in the optical imaging probe.
