PURPOSE:To effectively carry out cooling and cleaning of an air bearing by introducing pure air which has passed through an air cleaner into the above described air bearing part in means for loading an oil-free turbocharger utilizing the air bearing onto an engine. CONSTITUTION:A carbureter 80 is disposed between the oil-free turbocharger 30 utilizing an air bearing and an air cleaner 70. In this case, a take-out port 71 for pure air is provided between the air cleaner 70 and the carbureter 80. Further, an air port 46 to an air bearing part 41 is loaded onto the outer periphery at the substantially central part of a body 39. Communication holes 47 and 48 are formed in a body 39 and a cylinder 40, respectively, and circular grooves 49 and 50 are respectively formed on the inner peripheral surfaces of the body 39 and the cylinder 40. By this arrangement, upon actuation of the turbocharger 30, pure air which has passed through the air cleaner 70 is supplied to the air bearing part 41 through an take-out port 71 and an air port 46 and cooling and cleaning of the air bearing part 41 are carried out by the pure air. |
