Endoscope.

摘要

An endoscope includes a main body (4) for holding an operating mechanism in place and a casing (5) within which the main body is enclosed. The casing includes a hollow body-like casing body with one of its end portions serving to stabilize a base end of the main body and its other end portion having an opening portion permitting a protruded portion of the main body to be extended of the casing and a cylindrical gripping cover (7) having an end portion allowed to abut against the other end portion of the casing body and covering the protruded portion of the main body. The main body includes a nut (71) screwing engagement with an external thread (69) of the main body and engaged with a protruded portion (69) of the gripped cover, whereby the nut acts to urge the gripping cover toward the casing body and, at the same time, to urge the casing body toward the gripping cover, thereby pressing the end portion of the gripping cover and the other end portion of the casing body against each other.
