<p>Disclosed is an in-line skate with wheels arranged in three rows, which can allow a beginner or skilled person to conveniently and safely learn and use it, allow rapid turning at a rapid speed, and reduce load to the user's ankle. Moreover, the in-line skate has the auxiliary wheels having the outer diameter smaller than that of the main wheels, thereby reducing a rolling resistance due to unnecessary rolling of the auxiliary wheels. The in-line skate includes: a frame fixed on the bottom surface of a general shoe by means of bolts; a number of main wheels arranged on the center of the lower end portion of the frame in the longitudinal direction in a row; wheel shafts for fixing the plural main wheels onto the frame; and a number of auxiliary wheels fit on the wheel shafts and mounted at right and left sides of the main wheels, which are arranged in a row, the auxiliary wheels having the outer diameter smaller than that of the main wheels.</p> |
