摘要： A bearing includes a first bearing portion, a second bearing portion, and a connection portion. The first bearing portion assumes a generally C-like shape and opens in a first direction perpendicular to the rotational center axis. The second bearing portion assumes a generally C-like shape and opens in a second direction opposite the first direction. A gap is formed between the first and second bearing portions along the rotational center axis. The connection portion connects the first and second bearing portions at a position opposite the gap with respect to the rotational center axis.
