Abstract
A lubricating structure comprises an output gear 22 rotating as a unit with an output shaft 3 of a transmission mechanism, a gear 25 rotating as a unit with a counter shaft 27 and engaged with the gear 22, a gear 60 rotating as a unit with the shaft 27 and disposed spaced from the gear 25 in an axial direction, a bearing 26 and bearing 28b for rotatably supporting the shaft 27 respectively at a gear 25 side and a gear 60 side, a driving gear 65 disposed above the gear 60 and engaged with the gear 60 through an intermediate gear, a case 1a for individually accommodating through a separating wall the bearing 28b, a bearing at an intermediate gear side, and a bearing 67 at a gear 65 side, and feed paths 62,64 formed within the shaft 27 for introducing oil moved into an accommodating portion 70 of the gear 28b in the case 1a to a gear 25 side thereby to supply the oil to a predetermined portion. Furthermore, a void groove 76 is formed in the separating wall 69 between the accommodating portion 70 and an accommodating portion at an intermediate gear side.
