endoscope bendable curved in more than one direction with respect to the straight state a first curved portion having a tube, provided at the base end of the first curved portion and is bendable in multiple directions relative to the straight state, and in the same direction as the at least two directions of the first bending portion and it has a second curved portion having a second bent tube bendable, and the first bending drive mechanism for bending the first bending part in a plurality of directions and a second bending drive mechanism. The second bending drive mechanism and moves in conjunction with the first bend-driving mechanism and a first curved portion can be made to bend the second bending portion in a plurality of directions in a straight state, the bending angle of the first curved portion The upon increased relative to the straight state, to generate a compressive force in the bending direction side of the first curved portion with respect to the center axis C of the bending tube of the second curved portion.内視鏡は真っ直ぐの状態に対して複数の方向に湾曲可能な湾曲管を有する第1湾曲部と、第1湾曲部の基端側に設けられ、真っ直ぐの状態に対して複数の方向に湾曲可能であり、かつ、第1湾曲部の少なくとも2方向と同じ方向に湾曲可能な第2湾曲管を有する第2湾曲部と、第1湾曲部を複数の方向に湾曲させる第1湾曲駆動機構と、第2湾曲駆動機構とを有する。第2湾曲駆動機構は、第1湾曲駆動機構に連動して動き、第1湾曲部が真っ直ぐの状態で第2湾曲部を複数の方向に湾曲させることが可能で、第1湾曲部の湾曲角度を真っ直ぐの状態に対して増大させた際に、第2湾曲部のうち湾曲管の中心軸Cに対して第1湾曲部の湾曲方向側に圧縮力を発生させる。
