Claim:
1. A catheter comprising: a flexible shaft having a proximal portion and a distal portion opposed to the proximal portion along a longitudinal axis; a hub disposed at the proximal portion of the shaft; and a strain relief surrounding a predetermined proximal-side range of the shaft and including a distal end and a proximal end, and the distal end being closer to the distal portion of the shaft than the proximal end, wherein the distal end of the strain relief is configured such that the distal end of the strain relief is movable to be displaced along an axial direction of the shaft towards the proximal portion where the hub is located, the hub includes a storage chamber in which at least part of the strain relief is configured to be stored when the distal end of the strain relief is displaced along the axial direction of shaft, the storage chamber is opening to the distal side with respect to the shaft, the strain relief is spirally wound around the shaft, and the storage chamber includes a spiral-shaped groove configured to engage with the strain relief.
