To provide a hand cart configured so that a wheel is braked when a user of the hand cart converts a seating plate into a falling posture so as to surely prevent the user from falling when the user is seated and a structure of the device that brakes when the user is seated on the seating plate can be simplified to reduce costs.SOLUTION: A seating plate 2 that is converted to be able to stand and fall between a falling position and a standing position is supported rotatably between left and right steering frames 12, and a brake pad 32 which is pressure-contacted with an outer peripheral surface of each rear wheel 16 to be contactable and separable to perform braking is rotatably supported on a lower end of each rear-side leg body frame 17 through an arm 33. A link mechanism 4, which pressure-contacts the brake pad to the outer peripheral surface of each rear wheel when converting the seating plate into the falling position and separates the brake pad from the outer peripheral surface of each rear wheel when converting the seating plate into the standing position, is provided between a side farther from the brake pad than a horizontal axis 34 of the arm and the seating plate.SELECTED DRAWING: Figure 2
【課題】手押し車の利用者が着座板を倒伏姿勢に変換すれば車輪を制動させて、着座時に利用者の転倒を確実に防止するとともに、着座板に着座する際の制動装置の構造を簡単にして低廉化を図ることができる手押し車を提供する。【解決手段】左右の操舵フレーム12の間に、倒伏位置と起立位置とに起伏可能に変換される着座板2を回転自在に支持するとともに、各後側脚体フレーム17の下端に、各後輪16の外周面に対し接離可能に圧接して制動するブレーキパッド32をアーム33を介して回転自在に支持する。アームの水平軸34よりも反ブレーキパッド側と着座板との間に、着座板を倒伏位置に変換したときにブレーキパッドを各後輪の外周面へ圧接させる一方着座板を起立位置に変換したときにブレーキパッドを各後輪の外周面から離反させるリンク機構4を設ける。【選択図】図2
