PROBLEM TO BE SOLVED: To provide a transmission lubrication device capable of sufficiently reducing a quantity of lubricant while ensuring the supply of the lubricant to portions need to lubricate located at higher positions than a position of a lubricant supply source.SOLUTION: A transmission lubrication device lubricating portions 31 and 32 need to lubricate located at higher positions than a position of a lubricant supply source, comprises a lubricant supply passage provided between the portions 31 and 32 need to lubricate and the lubricant supply source, and is configured so that annular clearance throttles 13 and 14 are provided in downstream portions of the lubricant supply passage for restricting a flow volume of the lubricant, and the lubricant is supplied to the portions 31 and 32 need to lubricate by way of the annular clearance throttles 13 and 14, respectively. The downstream portions are at positions closer to the portions 31 and 32 need to lubricate than the lubricant supply source, respectively and preferably at positions near the portions 31 and 32 need to lubricate.SELECTED DRAWING: Figure 3 【課題】潤滑油供給源よりも高所に位置する要潤滑部に確実に潤滑油を供給しつつ、潤滑油量を充分に低減させることが可能な変速機の潤滑装置を提供する。【解決手段】潤滑油供給源よりも高所に位置する要潤滑部３１，３２を潤滑する変速機の潤滑装置は、要潤滑部と潤滑油供給源との間に設けられた潤滑油供給路を備え、潤滑油供給路の下流部には、潤滑油の流量を制限する環状隙間絞り１３，１４が設けられ、潤滑油は環状隙間絞りを通って要潤滑部に供給される。下流部は、潤滑油供給源よりも要潤滑部に近い位置であり、好ましくは前記要潤滑部の近傍の位置である。【選択図】図３
