摘要： In a lens unit 1, and an image sensing apparatus 15 incorporated with the lens unit 1 of the invention, a fixed cylinder 2 is formed with an oblong hole 21 extending in an optical axis direction in a lateral surface of the fixed cylinder 2. A driving force from a driving member such as a motor 12 is transmitted to a gear portion formed on an outer periphery of a cam cylinder 3 by a major axis gear 10 received in the oblong hole 21. Thereby, the cam cylinder 3 is rotated, and a lens holding frame is driven in the optical axis direction for a zoom operation. A pressing member 13 for pressing the major axis gear 10 in the optical axis direction during the zoom operation is provided at an end surface of the major axis gear 10.

摘要： A turbine hub has a through-hole extending through it in the axial direction. This through-hole is provided such that a portion of a thrust bearing covers part of the through-hole when the thrust bearing has been properly assembled onto the turbine hub, which enables assembly of the thrust bearing to be checked by the relative position relationship between the through-hole and the thrust bearing. If a portion of the thrust bearing does not cover part of the through-hole, it can be determined that either the thrust bearing is not assembled or that it has not been assembled properly.
