Abstract
In an endoscope apparatus, a suction button is detachable from a manual control part, and rubber parts such as O-rings and a knob are attached to the suction button. The rubber parts are made of a perfluoromonomer rubber material that is obtained by vulcanizing a material having a perfluoromonomer structure in which an average molecular weight is not greater than 2000. Thus, the rubber parts have excellent chemical resistance, heat resistance and mechanical strength. Therefore, the suction button can be both disinfected with new types of disinfectant having powerful oxidizing properties and sterilized in an autoclave.
