Abstract: A lubrication structure for a vehicle includes: a first lubrication pipe through which lubricating oil is supplied to a rotary machine disposed in a case; a second lubrication pipe through which lubricating oil is supplied to a bearing member disposed in the case; and an oil pump that supplies lubricating oil to the first and second lubrication pipes. The lubrication structure includes a first oil hole in the case that is connected to the first oil hole, and a second oil hole in the case, lubricating oil flowing into the second oil hole from the second lubrication pipe. A connection portion between the first lubrication pipe and the first oil hole is located above an opening portion of the second oil hole such that at least a part of lubricating oil that has flowed out from the connection portion flows into the second oil hole.
