<p>An elevator device, comprising a hoist installed on the rear wall surface of a hoistway in depth direction with the shaft of the motor part thereof positioned orthogonal to the rear wall surface and a return wheel disposed in a clearance between a cage and one lateral side wall surface of the hoistway rotatably around a horizontal shaft, joined to the drive pulley of the hoist through a hoist rope, and changing the rope arrangement direction of the hoist rope, wherein the rope groove pitch of the return wheel is formed larger than the rope groove pitch of the drive pulley, whereby, since the thickness of the drive pulley can be reduced by increasing the rope groove pitch of the return wheel joined to the drive pulley through the hoist rope and changing the rope arrangement direction of the hoist rope larger than that of the drive pulley, a clearance between the cage and the wall surface of the hoistway can be reduced to reduce a construction cost.</p> |
