| 1. A bearing unit comprising:
an anti-shaft-release member at a distal end of a shaft, said anti-shaft-release member being configured to prevent said shaft
from slipping in a thrusting direction;
a radial bearing configured to rotatably support said shaft, said shaft being radially revolvable within said radial bearing;
a space-forming member lid section covering a top surface of said radial bearing, a portion of said shaft extending from said
radial bearing through a hole within said space-forming member lid section;
a space-forming member main body surrounding a lateral surface of the radial bearing and a bottom surface of the radial bearing,
a portion of said space-forming main member body contacting said radial bearing;
a communication passage way configured to communicate said portion of said shaft with said distal end of said shaft, said
communication passage way being a void extending along said top, lateral and bottom surfaces.
