The present invention relates to a sprocket installation structure of an escalator reverse run prevention device. According to the present invention, the present invention proposes the sprocket installation structure, in which a pair of housings (300a) (300b) having a reception groove (302) surrounding a portion of a drive shaft (142) are provided, and sprockets halved on an outer circumference of at least one of the pair of housings (300a) (300b) are formed in a cross-sectional direction of the housings (300a) (300b), and the housing (300a) (300b) are fixed to the drive shaft (142) so that a stop wheel (360) is installed on the drive shaft (142). Accordingly, convenient operation and maintenance of fixing the stop wheel to the drive shaft is improved.

    본 발명은 에스컬레이터 역주행 방지장치의 스프로켓 설치구조에 관한 것으로, 구동축(142)의 일부를 감싸는 수용홈(302)이 형성된 한 쌍의 하우징(300a)(300b)이 구비되는 한편, 상기 한 쌍의 하우징(300a)(300b) 중 적어도 어느 하나의 외주에 반분된 스프로켓이 하우징(300a)(300b)의 횡단면 방향으로 형성되어, 상기 하우징(300a)(300b)이 구동축(42)에 고정됨으로써 스톱휠(360)이 구동축(142)에 설치되는 구조를 제안하여 스톱휠을 구동축에 고정하는 작업 및 유지보수의 편의성이 향상되도록 하는 에스컬레이터 역주행 방지장치의 스프로켓 설치구조에 관한 것이다.
