A lubricating-oil collection guide tool includes an oil-collection container; an oil funnel guiding lubricating oil into an oil passage at an axis end of a rotation axis; and an oil-passage member communicating the oil funnel and the oil-collection container. The oil-passage member includes a first passage member extending from the oil-collection container, and a second passage member extending from the oil funnel. While an insertion hole is formed in a lateral wall portion on one end side of the second passage member, one end portion of the first passage member is a cylindrical end portion. The cylindrical end portion is inserted into the insertion hole to move in and out in the axis line direction. The cylindrical end portion moves in a long axis direction relative to the insertion hole, and turns as a center of an axis line of the cylindrical end portion.
