<P>PROBLEM TO BE SOLVED: To provide an endoscope apparatus driving an optical system to be driven, backward and forward in a narrow cavity. <P>SOLUTION: The endoscope apparatus has a leaf spring 100 having: a fixed part 101 fixed to the optical system to be driven 63; an elastic part 102 having elasticity, extending from the fixed part 101; and a frictional engagement part 103 frictionally engaged with the outer circumferential surface of a driving member 61 with the elasticity of the elastic part 102. The elastic part 102 is formed to have a freely curved line in a plane perpendicular to a center axis 01, and has: a first elastic area 104 located in a relatively internal position in a case 31; a second elastic area 105, a part of which extends in parallel to the first elastic area 104, and located in a relatively outer position with respect to the first elastic area 104; and a bent part 106 by which the first elastic area 104 and the second elastic area 105 are connected together in a curved state. <P>COPYRIGHT: (C)2011,JPO&INPIT |
