PROBLEM TO BE SOLVED: To provide a hand scotch which can reliably prevent falling off and movement after attachment and hardly produces fluctuations in fastening power.SOLUTION: A hand scotch of a railway vehicle is provided with a main body block (11) having an inclination surface opposite to a flat mounting surface which can be brought into contact with a rail upper surface and a tread of a wheel of the railway vehicle, and is inserted between the tread of the wheel and the rail upper surface in order to prevent rolling of the wheel. Buffer material (12) joined to the inclination surface of the main body block, and an outside stationary bracket (13A) and an inside stationary plate (13B) which are joined to a lateral surface of the main body block and are extended downward so as to be located respectively on the outside and the inside of the rail are provided, a clamping pad which can be abutted on an inner lateral surface of the rail is fastened to a lower part of the inside stationary plate, a clamp member which can approach and separate for outside surface of the rail is mounted on the lower part of the outside stationary bracket, a clamp member is pressed against a rail lateral surface and the rail is held between the clamping pad and the clamp member and, thereby, is fixed.SELECTED DRAWING: Figure 1
【課題】取り付けた後の脱落や移動を確実に防止できるとともに、締結力にバラツキが生じ難い手歯止めを実現する。【解決手段】レール上面に接触可能な平坦な載置面および鉄道車両の車輪の踏面に対向する傾斜面を有する本体ブロック(11)を備え、車輪の踏面とレール上面との間に介挿されて車輪の転動を防止するための鉄道車両の手歯止めにおいて、本体ブロックの傾斜面に接合された緩衝材(12)と、本体ブロックの側面に結合されレールの外側と内側にそれぞれ位置するように下方へ延設された外側固定ブラケット(13A)および内側固定プレート(13B)とを設け、内側固定プレートの下部にはレールの内側面に当接可能なクランプ用パッドを固着し、外側固定ブラケットの下部にはレールの外側面に対して接近離反可能なクランプ部材を装着して、クランプ部材をレール側面に押圧させてクランプ用パッドとでレールを挟持することで固定させるように構成した。【選択図】図1
