To provide a simple mechanism of a truck which enables braking when travelling across a groove and parking.SOLUTION: In an auxiliary wheel and a brake mechanism of a truck which are excellent safety and operability, main wheels 2b, 2d for travel is provided and a fixation type auxiliary wheel 50 and at least one lifting type auxiliary wheel 100 are so juxtaposed near the main wheels, as to be floated upward with respect to the main wheels 2b, 2d, on a truck, a wheel 105 of the lifting auxiliary wheel 100 is so configured as to be a form which can fix lifting and rotation by operation of a pedal 121. It is excluded that the main wheels 2b, 2d, and a wheel of the fixation type auxiliary wheel 50 and the wheel 105 of the lifting auxiliary wheel 100 are simultaneously positioned on a groove when travelling on the groove, whereby fitting of wheels into the groove is avoided. When parking, the wheel 105 of which rotation is fixed is brought into pressure-contact with a floor surface, thereby enabling application of a brake.SELECTED DRAWING: Figure 8

    【課題】溝の横断走行と駐車時のブレーキが可能な簡便な台車の機構を提供する。【解決手段】台車に走行用の主車輪2b、2dと、その近傍に固定式補助輪50と少なくとも1個の昇降式補助輪100とを前記主車輪2b、2dより上方に浮かせて併設してあって、前記昇降式補助輪100の車輪105をペダル121の操作で昇降と回転を固定できる形態に構成し、溝上を走行する場合は、前記主車輪2b、2dと前記固定式補助輪50の車輪及び前記昇降式補助輪100の車輪105が同時に溝上に位置することを無くすことで車輪の嵌り込みを回避し、駐車する場合は、回転を固定した車輪105を床面に圧接することでブレーキを掛けることを可能にした安全性と操作性に優れた台車の補助輪及びブレーキ機構を提供する。【選択図】図8
