Abstract
A turbomachine of this disclosure includes a rotation shaft, a first impeller, a first bearing, and a second bearing. The first impeller is fixed to the rotation shaft and includes a low-pressure-side surface. The first bearing is adjacent to the low-pressure-side surface of the first impeller and supports the rotation shaft. The second bearing is disposed on an opposite side of the first impeller from the first bearing and supports the rotation shaft. The rotation shaft includes a first tapered portion gradually increasing in diameter toward the first impeller. The first bearing includes a first support surface supporting the first tapered portion.
