ABSTRACT:
A rigid type endoscope comprises an ocular and a rigid optic tube. The proximal end portion of the optic tube is inserted in a hollow connecting member connected to the ocular. An elastic holding mechanism is disposed between the connecting member and the proximal end of the optic tube for elastically holding the proximal end portion of the optic tube in the ocular. A transverse force exerted on the optic tube inserted in an object to be observed is distributed over the entire length of the proximal end portion of the optic tube by the elastic holding mechanism, thereby preventing the optic tube from being broken or permanently bent.
