PURPOSE:To obtain the subject wear having small total resistance of air applied to the wear by forming parallel groove lines on a required part of the surface of the wear and in front of the peeling position of boundary layer. CONSTITUTION:Parallel groove lines are formed on a required part of the surface of the wear and in front of the peeling position of boundary layer. The size, shape and number of the grooves are arbitrary. In the case of downhill one-piece wear, continuous or intermittent line of a groove M' is formed from the shoulder part 2 to the outside 3 of an arm, M'' at the inside of an arm, M''' from the outside 6 of a thigh to the outside 8 of a leg and M'''' from the inside 7 of a thigh to the inside 9 of a leg. |
