Abstract: The present invention provides a shipping method for guaranteeing that an article for shipping has remained sealed with a seal and has remained unopened. Specifically, first, the sender is asked to enter a signature on a seal. Because of the pressure from a writing implement at time of entering, the signature is copied to a sheet for verification. An article for shipping is sealed with a seal and transported to a recipient. The signature on the seal is verified against the signature on the sheet for verification. By confirming that the two match, it is confirmed that the seal has not been replaced. Thus it is guaranteed that the article for shipping has remained sealed with the seal and has remained unopened.

Abstract: A casing shaped from a light metal material by diecasting, the casing having formed at its inner wall surface a mounting portion having a circular inner surface, the mounting portion being adapted to receive a bearing member having a circular outer surface and serving to journal a shaft. The circular inner surface of the mounting portion has formed thereon a plurality of supporting protrusions spaced at predetermined intervals in the circumferential direction, and the bearing member is press-fitted into the mounting portion. Alternatively, the mounting portion into which the bearing member is to be press-fitted is defined by an annular protruding portion having formed therein a plurality of slits spaced at predetermined intervals in the circumferential direction.
