To provide a pulley device which can secure a wide operating range for a pulley when a fixed member is attached to a wall surface and can also be attached to a ceiling surface.SOLUTION: A pulley device includes a pulley body in which a sheave is rotatably supported between a pair of left and right side plates, a double shackle in which a pair of upper and lower shackles are connected by a swivel shaft so as to be rotatable relative to one another, and a mounting base to which the shackle is rotatably connected via the swivel shaft to the underside of a fixed plate. The double shackle is connected between the upper parts of the pair of left and right side plates of the pulley body and the shackle of the mounting base so as to be oscillating relative to one another by a connecting bar that passes horizontally through the double shackle. The lower shackle of the double shackle is spaced so as to sandwich the upper parts of the pair of left and right side plates of the pulley body, and the upper shackle is spaced so as to be sandwiched between the shackle of the mounting base.SELECTED DRAWING: Figure 1
【課題】固定部材を壁面に取り付けた場合には滑車の作動範囲を広く確保することができるとともに、天井面に取り付けることも可能な滑車装置を提供する。【解決手段】左右一対の側板の間にシーブを回転自在に支持した滑車本体と、上下一対のシャックルをスイベル軸によって相対回転自在に連結したダブルシャックルと、固定プレートの下面側にスイベル軸を介してシャックルを回転自在に連結した取付ベースとを備え、滑車本体における左右一対の側板の上部と取付ベースにおけるシャックルの間にダブルシャックルを水平に貫通する連結バーによって相対揺動自在に連結可能とした。また、ダブルシャックルにおける下側のシャックルは滑車本体における左右一対の側板の上部を挟み込み、上側のシャックルは取付ベースにおけるシャックルに挟み込まれる間隔とした。【選択図】図1
