Abstract
In this thesis, the result of the research that looked for the best shape of the circulation route of the end cap to reduce driving torque of a linear guide was put. The research that had been done this time experimented on the change when the curvature radius of the circulation route was changed. The result is brought together as follows. (1) It would be better to be composed only of the curve without mixing the straight line. (2) The frictional force has appeared like the wave. It is thought that it is because Wabing happens because the ball is faced with the end cap or the main body of the carriage, and the load cell had received it as an impact.
