To provide a medical device capable of reducing operation force of an operation part.SOLUTION: A medical device includes: a base unit equipped with a driving source and a connection part connected to the driving source; a bendable unit equipped with a bending part and a linear member configured so as to be connected to the connection part for bending the bending part by being driven by the driving source through the connection part; an operation part; and a deceleration mechanism equipped with an output member driven by the force transmitted from the operation part. The connection part includes a holding part that can transition between a holding state for holding the linear member and a release state in which the holding of the linear member is released, and a switching part that is moved by the output member for switching the holding part between the holding state and the release state. The output member is configured so as to move by a second moving amount smaller than a first moving amount when the operation part moves by the first moving amount.SELECTED DRAWING: Figure 11 【課題】操作部の操作力を低減可能な医療装置を提供する。【解決手段】医療装置は、駆動源と、前記駆動源に接続された連結部を備えるベースユニットと、湾曲部と、前記連結部に連結可能に構成され、前記連結部を介して前記駆動源によって駆動されることで前記湾曲部を湾曲させる線状部材と、を備える湾曲可能ユニットと、操作部と、前記操作部から伝達された力によって駆動される出力部材を備える減速機構と、を有する。前記連結部は、前記線状部材を保持する保持状態と、前記線状部材の保持が解除された解除状態と、の間で遷移可能な保持部と、前記出力部材によって移動され、前記保持部を前記保持状態と前記解除状態との間で切り換える切換え部と、を備える。前記出力部材は、前記操作部が第１の移動量だけ移動した場合に前記第１の移動量よりも小さい第２の移動量だけ移動するように構成される。【選択図】図１１
