PURPOSE: A portable sliding resistance measuring device is provided to make an automatic measurement possible, to enhance the reliability of a measurement result, and to reduce power consumption. CONSTITUTION: A portable sliding resistance measuring device comprises a body(100), a driving unit(110), a load block(130), a push pull gauge(120), and a connection unit(140). An opening is formed in the body. The driving unit comprises a replaceable battery, a linear motor and a forward-backward switch. The load block comprises a block body, a plurality of bearings, and a rubber sensor. The block body is arranged in an opening area of the body. The bearing is arranged in the one side of the block body, thereby roll-contacting to the ground through the opening area. The rubber sensor is arranged in the other side of the block body and contacts to the ground, thereby being supported. The push pull gauge is mounted on the block body of the load block, thereby measuring a coefficient of static friction. The connection unit connects the driving unit and the load block.
