PURPOSE:To lubricate the gear shaft supporting part of a counter shaft without forming an oil passage by allowing the case joint surface of an oil pump from which lubricating oil leaks and a shaft hole formed on the shaft having the gear shaft supporting part to communicate with each other. CONSTITUTION:When the input shaft of a belt type continuously variable transmission is revolution-driven, also an oil pump 61 is driven, and oil is supplied from a discharged port into each part. The lubricating oil pumped up inside the pump leaks through the joint surface 63d of a pump case 63, and a portion intrudes into a lubricating oil passage 63c formed on a case 63a through the space 63e between ribs, and is introduced into the shaft hole of a counter shaft and lubricates a gear shaft supporting part. Therefore, the lubrication for the gear shaft supporting part of the counter shaft which is achieved with a relatively small quantity of lubricating oil can be carried out by the lubricating oil which leaks from the case joint surface of the oil pump, and a lubricating oil feeding passage can be formed in simple ways without forming a special oil passage.
