To provide a parking brake member where a side pressure contact part 70 does not interfere with a main wheel 2 when the main wheel 2 of a wheelchair 1 is exchanged.SOLUTION: A parking brake member 50 includes a position change mechanism 51 for allowing a side pressure contact part to be changed in position to be in a state at a normal use position α where the side pressure contact part 70 is opposed to a side surface of a tire of a main wheel 2 and the side pressure contact part 70 can have pressure contact with a side surface of a tire of the main wheel 2 when a parking brake is operated or at a wheel exchangeable position β where the side pressure contact part 70 is positioned on an outer side from the most outer peripheral part of a tire of the main wheel 2 so as not to be opposed to a side surface of the tire.SELECTED DRAWING: Figure 10
【課題】車いす1の主車輪2を交換する際にサイド圧接部70が主車輪2と干渉しない駐車ブレーキ部材を提供する。【解決手段】駐車ブレーキ部材50は、サイド圧接部70が主車輪2のタイヤのサイド面に対向しており、駐車ブレーキ操作時に当該主車輪2のタイヤのサイド面にサイド圧接部70が圧接可能とされている通常使用位置αと、サイド圧接部70が当該主車輪2のタイヤの最外周部よりも外側に位置して当該タイヤのサイド面に対向していない車輪交換可能位置βと、のいずれかの状態に位置変換させる位置変換機構51を有している。【選択図】図10
