Abstract: There is provided a bending portion for an endoscope and the endoscope which can prevent the piece fall of bending pieces without enlarging the diameter of the bending portion and raising the filling rate of built-in components in the bending portion. In the bending portion, one bending piece of adjacent bending pieces is formed so that a cross-sectional shape is, for example, an elliptic shape whose major axis direction or minor axis direction corresponds to a first direction. The other bending piece of the adjacent bending pieces is formed so that a cross-sectional shape is, for example, a circular shape in which a length in the first direction differs from the first bending piece; and an abutting portion in which their end portions facing each other of the adjacent bending pieces abut on each other in at least two points when the bending portion is bent.

Abstract: A tube assembly for an endoscope includes a steering device and a flexible tube device on a proximal side. The tube assembly includes an inner sleeve. An outer sleeve receives one end portion of the inner sleeve in an axial direction, for connection of the flexible tube device to the steering device. A flow opening is formed in a portion of the outer sleeve disposed around the inner sleeve. A distribution groove is formed between an outer wall surface of the inner sleeve and an inner wall surface of the outer sleeve, to extend from the flow opening. A seal cavity is formed in the inner and outer sleeves to extend from the distribution groove in a direction away from the flow opening. Flowing solder material is supplied in the flow opening, charged in the distribution groove and the seal cavity, for attaching the outer sleeve to the inner sleeve.
