The endoscope connector includes a light source side fitting portion that is detachably fitted to a light source device having an emission end that emits illumination light for irradiating a subject, and illumination light from the light source device in a fitted state. An incident portion that is incident, a transmission portion that transmits illumination light incident on the incident portion, and an endoscope-side fitting portion that detachably fits an endoscope having an incident end on which the illumination light is incident A light emitting portion that emits the illumination light transmitted by the transmission portion to the incident end of the endoscope in the fitted state, and the light of the illumination light in the fitting portion corresponding to one of the incident portion and the light emitting portion And a holding mechanism that holds the movable portion in a vertical direction perpendicular to the axial direction or the optical axis direction.内視鏡用コネクタは、被写体に照射するための照明光を出射する出射端を有する光源装置に着脱可能に嵌合する光源側嵌合部と、嵌合の状態において光源装置からの照明光が入射される入射部と、入射部に入射された照明光を伝送する伝送部と、照明光が入射される入射端を有する内視鏡が着脱可能に嵌合する内視鏡側嵌合部と、嵌合の状態において伝送部によって伝送された照明光を内視鏡の入射端に出射する出射部と、を有し、入射部および出射部の一方に対応する嵌合部において照明光の光軸方向又は光軸方向に垂直な垂直方向に移動可能に保持する保持機構とを有する。
