To provide a catheter easy to operate for deviating a tip end of a catheter shaft.SOLUTION: The catheter is so configured that, when a handle operation part 5 is moved to a distal side or a proximal side, in association with a rack part 71 sliding toward the distal side or the proximal side, a gear part 72 rotates along a first tooth 711, and then, a pull wire 73 is wound up on the gear part 72, so that a tip end side of a catheter shaft 2 is pulled to be able to deviate, where a pulled distance of the catheter shaft by the pull wire is smaller than a move distance of the handle operation part.SELECTED DRAWING: Figure 2 【課題】カテーテルシャフトの先端部の偏向のための操作が容易なカテーテルを提供することを提供すること。【解決手段】カテーテルは、ハンドル操作部５を遠位側または近位側に動かすと、ラック部７１が遠位側または近位側に向かって摺動するに伴って、歯車部７２が第１歯７１１に沿って回転し、プルワイヤー７３が歯車部７２に巻き取られることでカテーテルシャフト２の先端側が引っ張られて偏向可能であるとともに、プルワイヤーによるカテーテルシャフトの引張距離が、ハンドル操作部の移動距離よりも小さい。【選択図】図２
