PROBLEM TO BE SOLVED: To prevent an inadvertent caster turning of a front wheel when folding a folding-type baby carriage.SOLUTION: A folding type baby carriage includes: a caster lock member (24) which is provided on a caster holding member (22) and which restricts rotation of a caster rotary member (23) at a lock position C and permits rotation of the caster rotary member at a release position A; an elastic member (25) which energizes the caster lock member from the lock position C to the release position A; and operation members (26, 27) of which one end is connected to the caster lock member and the other end is disposed on a vehicle body frame, and which operates the caster lock member to a lock limit position B against an energization force of the elastic member by contact of the other end thereof with form change portions (6, 8, 28) of the vehicle body frame which changes a form from a developed state to a folded state.
【課題】折畳式乳母車の折り畳み操作時に前輪が不用意にキャスタ転回することを防止する。【解決手段】折畳式乳母車は、キャスタ保持部材(22)に設けられ、ロック位置Cでキャスタ回動部材(23)の回動を規制し、解除位置Aでキャスタ回動部材の回動を許容するキャスタロック部材(24)と、キャスタロック部材をロック位置Cから解除位置Aへ付勢する弾性部材(25)と、一端がキャスタロック部材と連結し、他端が車体フレームに配置される部材であって、展開状態から折り畳み状態へ形態変化する車体フレームの形態変化箇所(6,8,28)が他端と当接することにより弾性部材の付勢力に抗してキャスタロック部材をロック限界位置Bにする作動部材(26,27)とを備える。【選択図】図5
