PROBLEM TO BE SOLVED: To provide a wheel stopper capable of disabling independent rotation of a pair of wheels with one operation.SOLUTION: A wheel stopper body 11 supports a wheel rotation shaft 2a for a pair of wheels 2 and each wheel 2 is equipped with an engagement hole. The wheel stopper body 11 is equipped with a pair of lock pins 12 each of which engages with the engagement hole to disable rotation of the wheel 2. A compression coil springs 13 are provided, each of which urges the lock pin 12 independently toward the engagement hole. A rotary plate 15 is provided rotatably around a rotary shaft 14 provided on the wheel stopper body 11. Each lock pin 12 is abutted to the rotary plate 15 to keep the lock pin 12 free from engagement with the engagement hole. The rotary plate 15 is provided with a control lever 17 that rotates the rotary plate.SELECTED DRAWING: Figure 7
【課題】車輪ストッパにおいて、1つの操作で一対の車輪を独立して回転不能にする。【解決手段】車輪ストッパ本体11に一対の車輪2の車輪回転軸2aを支持し、一対の車輪2に係合孔をそれぞれ設ける。車輪ストッパ本体11に係合孔に係合して車輪2を回り止めする一対のロックピン12をそれぞれ設ける。一対のロックピン12をそれぞれ独立して係合孔側へ付勢する圧縮コイルバネ13を設ける。車輪ストッパ本体11に設けた回動軸14を中心に回動板15を回動可能に設け、この回動板15に一対のロックピン12をそれぞれ当接させ、各ロックピン12を係合孔に対して係合していない状態に保つ。回動板15に、この回動板を回動操作する操作レバー17を設ける。【選択図】図7
