<P>PROBLEM TO BE SOLVED: To provide a lubricating oil passage structure in an automatic transmission capable of adjusting the amount of lubricating oil supplied to a speed change mechanism via an oil passage of an input shaft. <P>SOLUTION: The lubricating oil supplied from an oil pump is supplied to oil holes 20 and 21 of the input shaft 3 rotating with an one-way rotary direction ω by means of rotation of a drive source so as to receive it through through-holes 11d and 11d of a fixed sleeve member 11, and is supplied to the speed change mechanism arranged at an axial direction via the oil holes 20 and 21. When the through-holes 11d and 11d are drilled at a drilling direction C of an angle θ1 slant to a forward rotary direction of the rotary direction ω against a radial direction B of an axis CT, the state on a direction receiving oil pressure of the lubricating oil at an arrow H direction (the state on a position from the oil hole 21 to the oil hole 21') keeps longer. When the through-holes 11d and 11d are drilled at a drilling direction D of an angle θ2 slant to a backward rotary direction of the rotary direction ω, the state on a direction receding from oil pressure of the lubricating oil at an arrow I direction (the state on a position from the oil hole 21' to the oil hole 21") keeps longer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
