In addition, in illustrated example, the opening surface 60a that forms the side that makes base plate 70 and main body cover 60 is on 2 locate butt structures, but is not limited to this, both can form the structure of locating butt at 1, perhaps can form again in the structure of locating butt more than 3 o'clock.
Preferably, locate, promptly locate butt axisymmetric 2 of cylindrical member 72 at least with respect to axisymmetric 2 of the drag force that bottom board unit 64 is applied.Thus, can not produce with the abutting part is the rotation of fulcrum, and can prevent because of rotating the dislocation of caused main body cover and base plate.
In addition, in illustrated example, the opening surface 60a of main body cover 60 contacts in planar mode with abutting member 68 (abutting part 104), but be not limited to this, both can carry out the line contacting structure for the opening surface 60a and the abutting member of main body cover 60, perhaps again can be for carrying out a contacting structure.For example, abutting member, also can form sphere with the face of main body cover 60 butts.
Then, the assembling about the operating portion 14 of endoscope 10 is described in detail.
At first, insert the base plate 70 of bottom board unit 64 from the peristome of the opening surface 60a that is formed on main body cover 60.Assigned position in main body cover 60 configuration base plate 70, and the opening surface 60a of main body cover 60 and base plate 70, dispose abutting member 68 between with the aspectant side of opening surface 60a, thereby base plate 70 is arranged in the main body cover 60.
Then, the fixed axis 78 that will carry out the operating mechanism of bending operation passes configuration to the 60b of open pore portion of main body cover 60, and fixed axis 78 is fixed on the base plate 70 of bottom board unit 64 by hold-down screw 76a.And then, the parts of other of fitting operation mechanism.
Then, be configured to cover with controlling housing 62 from the cylindrical member 72 of the outstanding bottom board unit 64 of the peristome of main body cover 60 and the protuberance 70a of base plate 70.Afterwards, the retainer ring 66 and the outer screw section 72a of cylindrical member 72 are screwed togather, and will control housing 62 and remain the state of pushing to the main body cover side by retainer ring 66.
Thus, main body cover 60, control housing 62, fixed axis 78 (operating mechanism) is firmly fixed.
At this, by the retainer ring 66 that the cylindrical member 72 with bottom board unit 64 screws togather, will control housing 62 and push to main body cover 60 sides, therefore, bottom board unit 64 is pulled to retainer ring 66 sides (insertion section 12 sides) by counter-force.
But in endoscope 10 of the present invention, the side of the base plate 70 of bottom board unit 64 and the opening surface 60a of main body cover 60 be butt via abutting member 68.Thus, even if bottom board unit 64 is dragged to retainer ring 66 laybacks, can not produce the dislocation of bottom board unit 64 (base plate 70) and main body cover 60 yet.Thereby, eliminate the situation of the action variation of the crooked or operating mechanism of operating portion 14 globalities, and can realize reliable operation.
More than, explain about endoscope of the present invention, but the present invention is not limited to the foregoing description, in the scope that does not exceed purport of the present invention, can certainly carry out various changes or improvement.
