PROBLEM TO BE SOLVED: To solve such a problem that when a pair of car lower pulleys are inclined and disposed without being parallel to the opening and closing direction of a car door, the protruding amount of the car lower pulleys from a car is increased and a hoistway area necessary for installing an elevator is increased.SOLUTION: An elevator device of the present invention is configured as follows: car lower pulleys 3, 4 are provided as one pair in an inclined direction not parallel to an opening and closing direction of a car door 11, and provided so that a centroid of the car 11 is positioned on a straight line connecting the paired pulleys 3 and 4; each of the paired car lower pulleys 3, 4 has a plurality of pulleys 3a, 3b, 3c and 4a, 4b, 4c, respectively; diameter dimensions of the plurality of pulleys 3a, 3b, 3c are different from each other and diameter dimensions of the plurality of pulleys 4a, 4b, 4c are different from each other; and a sum of the diameters of the paired pulleys 3a and 4a, a sum of the diameters of the paired pulleys 3b and 4b, and a sum of the diameters of the paired pulleys 3c and 4c, each of the pairs being wound by the identical main rope 14, become equal to each other. |
