To provide an escalator emergency brake device capable of further ensuring blocking of rotation of a main spindle.SOLUTION: This escalator emergency brake device is configured such that a ratchet pole 9 fixed to a rotating shaft 3 is engaged with a ratchet wheel 10 in association with rotation of a shoe lever 6 when a driving chain 7 is broken and the shoe lever 6 rotates. The escalator emergency brake device is provided with: a weight support member 112 that is displaced in association with the rotation of the shoe lever 6; and an auxiliary weight 113 that is supported by the weight support member 112. The auxiliary weight 113 pushes the shoe lever 6 toward a direction where the ratchet pole 9 is engaged with the ratchet wheel 10 when the weight support member 112 is displaced and the supporting of the auxiliary weight 113 by the weight support member 112 is released.SELECTED DRAWING: Figure 2

    【課題】主軸の回転をより確実に阻止することができるエスカレーター非常制動装置を得る。【解決手段】駆動チェーン7が破断し、シューレバー6が回動した場合に、シューレバー6の回動に連動して回転する軸3に固定されたラチェットポール9がラチェットホイール10に噛み合うエスカレーター非常制動装置であって、シューレバー6の回動に連動して変位するおもり支持部材112と、おもり支持部材112に支持された補助用おもり113とを備え、補助用おもり113は、おもり支持部材112が変位し、おもり支持部材112による補助用おもり113の支持が解除された場合に、ラチェットポール9がラチェットホイール10に噛み合う方向にシューレバー6を押す。【選択図】図2
