い。For example, in Japanese Patent Publication No. 3-78300, a pair of front and rear wheel supports are horizontally rotatably supported on the lower surface of the bogie main body. In addition to this, a pair of guide wheels that rotate horizontally in the vicinity of each running wheel is provided with a rail interposed therebetween, and a transport vehicle configured to be able to travel while securing an appropriate guiding function even on a curved track with a small radius of curvature is provided. Have been described. By the way, in this type of transport trolley, the guide wheels are gradually worn while repeating contact with the rails. Therefore, in order to obtain an appropriate guide function by the guide wheels, a gap between the pair of guide wheels and the rails is required. Need to be adjusted periodically. Further, in order to ensure an appropriate guide function by the guide wheels, it is necessary to adjust the gap between the pair of guide wheels and the rail to be equal.

The initial guidance function using wheels cannot be obtained. On the other hand, various guide wheel gap adjusting devices for adjusting a gap between a pair of guide wheels and a rail have been proposed, but in a conventional guide wheel gap adjusting device, a pair of guide wheels are independently moved to adjust. serves to way, one-to-guide wheel and the work a gap is adjusted to so that matte equally between rails very difficult, working efficiency has a problem that extremely low. Further, the guide wheel can be fixed only at the position where the guide wheel is moved stepwise, and there is a problem that the gap between the pair of guide wheels and the rail cannot be precisely adjusted.
