Abstract:
1. An oil discharge structure of a baffle plate, comprising: a transmission case that defines a rotating body chamber at least partially filled with oil; a first rotating gear; a second rotating gear, meshed with the first rotating gear, the second rotating gear having a rotating axis above that of the first gear; an oil reservoir provided separately from the rotating body chamber to store oil discharged from the rotating body chamber; an oil discharge path from the rotating body chamber to the oil reservoir through an opening provided in a side of the transmission case; and a baffle plate placed between the transmission case and the first gear in the rotating body chamber to surround the first gear along a circumferentially whole part which is immersed in the oil so that oil in the circumference of the first gear is divided into a gear side and a transmission case side in the rotating body chamber; wherein the baffle plate includes an inlet side end, which is an end of the baffle plate in its circumferential direction where the circumference of the first gear in a rotating state is coming into the space within the battle plate, an outlet side end which is an end of the baffle plate in its circumferential direction where the circumference of the first gear in a rotating state is going out from the space within the baffle plate, and an oil discharge hole formed closer to the inlet side end of the baffle plate than the outlet side end of the baffle plate and facing a side face of the first gear; and wherein the oil discharge hole faces the opening in the side of the transmission case, so that the oil in the first gear side divided by the baffle plate is discharged through the oil discharge hole to the oil discharge path.
