PROBLEM TO BE SOLVED: To perform variable control of a supply amount of lubricant oil for every lubricant oil supplier without using any exclusive hydraulic control valve for every lubricant oil supplier.SOLUTION: An automatic transmission is provided with a rotary valve 30 including a rotary valve main body 31 having an input port [e] to which lubricant oil is inputted and a plurality of output ports [f] for outputting lubricant oil to a plurality of lubricant oil suppliers and a valve body 32 for selectively communicating the input port [e] with the plurality of output ports [f]. The rotary valve main body 31 is formed with a plurality of opening ports communicated with the plurality of output ports [f], extending in a peripheral direction of the valve body 32 and spaced apart in a radial direction of the valve body 32, and the valve body 32 is formed with a communicating part for being rotationally driven and selectively communicating the input port [e] with the plurality of output ports [f] to control supply of lubricant oil to the plurality of lubricant oil suppliers.SELECTED DRAWING: Figure 5

    【課題】潤滑油供給先ごとに専用の油圧制御弁を用いることなく、潤滑油の供給量を潤滑油供給先ごとに可変制御するようにする。【解決手段】自動変速機に、潤滑油が入力される入力ポートeと複数の潤滑油供給先に出力する複数の出力ポートfとを有するロータリー弁本体31と、入力ポートeと複数の出力ポートfとを選択的に連通させる弁体32とを有するロータリー弁30が備えられ、ロータリー弁本体31に、複数の出力ポートfに連通されると共に弁体32の周方向に延在し、且つ弁体32の径方向に離間して配置される複数の開口部が形成され、弁体32に、回転駆動させることにより入力ポートeと複数の出力ポートfとを選択的に連通させて複数の潤滑油供給先への潤滑油の供給を制御する連通部が形成される。【選択図】図5
