To determine an inclination angle of a car with a simple structure.SOLUTION: An inclination angle determination device 50 includes: a disk-shaped base 51 with a trapezoidal cross section which has a bottom surface 52 in contact with a floor surface of a car; a spherical depression 53 provided at a top part facing the bottom surface 52; and a spherical body 55 which is rollably placed on the depression 53. An angle θ in a tangential direction to the bottom surface 52 of an edge 54 of the depression 53 is a determination angle. When the inclination of the floor surface of the car exceeds a standard value of inclination, the spherical body 55 rolls down from the depression 53.SELECTED DRAWING: Figure 3
【課題】簡便な構成でかごの傾斜角度を判定可能とする。【解決手段】傾斜角度判定器50は、かごの床面に接する底面52を有する台形断面の円板状のベース51と、底面52に対向する頂部に設けられた球面状の窪み53と、窪み53に転動自在に載置された球体55と、を備え、窪み53の縁54の底面52に対する接線方向の角度θが判定角度となっている。かごの床面が傾斜の基準値を超えて傾斜した場合には、球体55が窪み53から転がり落ちる。【選択図】図3
