BELT DRIVE MECHANISM AND AUTOMATIC DOOR DEVICE
To provide a belt drive mechanism capable of preventing occurrence of noise due to contact of a toothed belt with a flange of a drive pulley even in a long-term use, and an automatic door device into which the belt drive mechanism is incorporated.SOLUTION: A belt drive mechanism comprises: an elastic toothed belt 40 with a square cross section; a drive pulley 20 in which a tooth tip surface 22a and a tooth bottom surface 22b have the same curved surface shape in which the height gradually decreases from both end parts 20a and 20a toward a center part 20b so that the center part 20b having a width from both end parts 20a and 20a in the direction of an axis 23 is the lowermost bottom, and which transmits power of a drive motor 10 by engagement to the toothed belt 40 which is annularly bridged with a driven pulley 30.SELECTED DRAWING: Figure 3
【課題】長期の使用においても歯付きベルトが駆動プーリーのフランジに接触することによる異音の発生を防ぐことができるベルト駆動機構、および、ベルト駆動機構を組み込んだ自動ドア装置を提供すること。【解決手段】弾性を有する断面四角形状の歯付きベルト４０と、歯先面２２ａおよび歯底面２２ｂが、両端部２０ａ、２０ａから軸２３方向の幅の中央部２０ｂが最底となるように両端部２０ａ、２０ａから中央部２０ｂに向けて漸次高さが低くなる同一の曲面形状をなし、駆動モーター１０の動力を、従動プーリー３０との間で環状に架け渡される歯付きベルト４０に噛み合い伝動する駆動プーリー２０と、を有する。【選択図】図３
