The entry mechanism of solid particle to the interface between sliding surfaces in unlubricated condition was experimentally investigated by the in-situ observations of entry processes with optical microscope. The number of solid particles which entered to the interfaces between sliding surfaces immediatelly decreased at a certain entrance angle of pin specimen. This entrance angie was named critical entrance angle. The critical entrance angles were changed with the surface roughness of sliding surfaces, the materials of specimens and the load. It was found that the roughness, the materials of specimens and the load affected the friction coefficient between particle and sliding surface and the deformation of specimens respectively. And we discussed the results with the simple model which neglected the deformation of specimens. Then we compared expeimental values of critical entrance angle and theoritical values based on the model.
