A vertical drum type wind generator is provided to reduce noise generated from supporting clothes of wings when the clothes are collided with the external air while a large cylindrical wind generator rotates. A vertical drum type wind generator comprises an outer support structure, a rotation cylinder(210), a rotation shaft(260), an upper bearing(320), a lower bearing(330), a plurality of wings(220), and a wing fitting mold(290). The wind generator allows the wings to make contact with an outer peripheral of the rotation cylinder based on the positions of the wings with respect to the wind. The outer support structure is connected to an upper bearing received in the lower bearing and a lower bearing(340) received in an upper bearing housing(350). The rotation cylinder is fixedly installed at a center shaft(260), which is connected to the outer support structure. |
