Tracked moving apparatus

The present invention shear pulley unit which is provided on the front end side of the main body; After the main body of the rear pulley unit are provided in the end side; A power transmission belt that is wound around the outer periphery of the front end and the rear end pulley unit pulley unit; And is incident on the front end roller pulley unit and the rear end pulley along forward and backward directions between the unit includes a plurality of support roller unit connected to the side of the main body, the plurality of support roller units; And one end is connected to the main body, the other end of the support roller is provided with a spring which is rotatably connected, at least one of the support roller unit out of the plurality of support rollers unit when greater in than the other support roller unit to apply a contact pressure can provide a track-type mobile device according to claim. According to the invention, it is possible to reduce the rotational friction of the ground which occurs during the turning of the track-type mobile device, makes it so that the track-type mobile device can be smoothly or seamlessly turning in place, the sharp steering through.
