PROBLEM TO BE SOLVED: To improve lubrication performance relative to each portion by controlling lubrication amount of lubricating oil relative to each portion requiring lubrication.SOLUTION: A lubrication device for a vehicle includes: a first shaft 5 formed to have a cylindrical shape and having a supply passage 9 penetrated between an inner peripheral surface 5a and an outer peripheral surface 5b; and a second shaft 11 that has one portion provided as an insertion portion 15 inserted into the first shaft and the other portion provided as a protruded portion 16 protruded axially from the first shaft and that is movable in the axial direction relative to the first shaft while an outer peripheral surface of the insertion portion comes into contact with the inner peripheral surface of the first shaft. A flow passage 14 in which lubricating oil is made to flow is provided at a position leading from the insertion portion to the protruded portion, and a first outflow passage 17 connected to the flow passage and making the lubricating oil flow out to outside via the supply passage is formed in the insertion portion. A second outflow passage 18 connected to the flow passage and making the lubricating oil flow out to outside is formed in the protruded portion. The supply passage is opened/closed by the insertion portion according to the movement position of the second shaft relative to the first shaft.SELECTED DRAWING: Figure 5 |
