Abstract
The invention relates to a double roller () with two running wheels () and one carrier housing (), wherein an assembly journal () is arranged on the carrier housing (). An actuating tappet () can be displaced in the assembly journal against a spring force, interacting with a counter locking part () for directional and/or complete fixation. Furthermore, a running wheel braking part () with engaging parts () is provided for blocking the rotation of the running wheels (). The running wheel braking part () is likewise actuated by the actuating tappet () and furthermore the housing section () accommodating the actuating tappet () includes a ball bearing () on the upper side and surrounds the actuating tappet () at least partially toward the bottom. In order to enhance a double roller of this type, it is proposed to have the counter locking part () inserted underneath the ball bearing () in the part of the housing section () that opens only in regard to the inner opening.
