PROBLEM TO BE SOLVED: To provide a carriage that is configured to prevent a lock lever part from protruding rearward from a backside of the carriage and thereby prevent the lock lever part from contacting an obstacle, can secure safety of an operator and the carriage at the time of conveying and stopping the carriage and can be stored or housed with a space saved.SOLUTION: At the time of locking, a lock lever part of a rotary body is rotated and then a cam part of the rotary body increases a pushing-in width in the width direction of a wheel lock pin against elastic force of a pressing spring, so as to move the wheel lock pin in a width direction of a carriage and engage an end part of the wheel lock pin with a recessed part of a wheel. At the time of unlocking, the lock lever of the rotary body is rotated in the opposite direction of the direction at the time of locking, and the cam part of the rotary body reduces the pushing-in width in the width direction of the wheel lock pin, and the pressing spring presses a flange part of the wheel lock pin and a wheel-side pivoting part by elastic force thereof, so as to prevent the end part of the wheel lock pin from engaging with the recessed part of the wheel.SELECTED DRAWING: Figure 1

    【課題】ロックレバー部が台車の裏面から後方に飛び出ることはないことにより、ロックレバー部が障害物に接触することを防止し、台車の運搬時や停止時において、作業者及び台車の安全を確保することが可能となるとともに、省スペースでの保管又は収納が可能となる台車を提供する。【解決手段】ロック時に、回転体のロックレバー部を回転させ、回転体のカム部が、押圧スプリングの弾性力に抗して車輪ロックピンの幅方向の押し込み幅を増加させることにより車輪ロックピンを台車の幅方向に移動させ、車輪ロックピン端部が車輪の凹部に歯合するようにし、アンロック時に、回転体をロック時と逆方向にロックレバーを回転させ、回転体のカム部が車輪ロックピンの幅方向の押し込み幅を減少させ、押圧スプリングがその弾性力により車輪ロックピンの鍔部と車輪側軸支部を押圧することにより、車輪ロックピン端部が車輪の凹部に歯合しないようにする。【選択図】図1
