Abstract:
The purpose of the invention is to reduce bearing loss due to lubricating oil. This invention comprises: a rotary shaft (14); a journal bearing (22) that is provided to the rotary shaft (14) and that rotatably supports the rotary shaft (14); a flange part (17b) having an opposing surface part (17bb) that is arranged so as to oppose a side surface part (22d) of the journal bearing (22) with a gap (D) therebetween in the axial direction in which the rotary shaft (14) extends; and a recess part (22e) provided in the side surface part (22d) or the opposing surface part (17bb). In the projected area of the journal bearing (22) in the axial direction, the area of a section including the recess part (22e) and not forming the gap (D) is larger than the area in which the side surface part (22d) and the opposing surface part (17bb) form the gap (D).
