Fundamental experiments on fluid leakage from the tapered seal by sleeve rotation were performed. The apparatus was so designed that surface tension, which generates the sealing function, acts adequately in size and accuracy as similar as in an actual device. The shapes of the meniscus at several rotational speeds were measured by using ultra-focus laser microscope, and the features of fluid leakage were observed by using high-speed camera. The experimental results of the positions of the bottom portions of the meniscus coincide comparatively well with theoretical ones. It is also verified that the experimental threshold speeds of fluid leakage occurrence can broadly be estimated by the theoretical 'ultimate' and 'triggering' critical rotational speeds of the sleeve rotor.
