Relates to an electric bending endoscope bending portion is actuated to be bent by an electric, an object of the present invention to provide an electric bending endoscope which allows the operation feeling similar to the mirror manually bending endoscope. In the electric bending endoscope, the drive unit (37), a drive transmission mechanism for transmitting a driving force generated driving unit for generating a driving force (64), driver (64) A (65), and a drive transmission mechanism including the drive connection (61) to (65), the driven unit (31), the curved portion (34), a driven transmission mechanism for transmitting a driving force to (34) curved portion ( A 55), the driving force to (55) driven transmission mechanism from (65) the driving transmission mechanism is connected to the drive coupling part (61) when mounted a driven unit (31) to (37) the drive unit has driven transmitting mechanism comprising a driven coupling part which allows transmission of the (48), and (55), drive unit (37), the detection unit for detecting a load driven transmission mechanism (55) (87 I have).本発明は、電動により湾曲部が湾曲作動される電動湾曲内視鏡に関し、手動湾曲内視鏡と同様な操作感覚を可能とする電動湾曲内視鏡を提供することを目的とする。電動湾曲内視鏡では、駆動ユニット(37)は、駆動力を発生する駆動部(64)と、駆動部(64)で発生された駆動力を伝達する駆動伝達機構(65)であって、駆動連結部(61)を備える駆動伝達機構(65)と、を有し、従動ユニット(31)は、湾曲部(34)と、湾曲部(34)へと駆動力を伝達する従動伝達機構(55)であって、駆動ユニット(37)に従動ユニット(31)が装着される場合に駆動連結部(61)と連結されて駆動伝達機構(65)から従動伝達機構(55)へと駆動力を伝達可能とする従動連結部(48)を備える従動伝達機構(55)と、を有し、駆動ユニット(37)は、従動伝達機構(55)での負荷を検知するための検知部(87)を有する。
