Abstract
In a belt continuously-variable transmission, a casing or a housing is formed with an air communicating hole extending through an upper part of the casing or the housing. The casing and the housing include inner walls defining an air breather chamber and communicating parts. The air breather chamber is defined in a region located above a joint between the casing and the housing and ranging from an upper side of the second shaft to an upper side of the first shaft and between the second shaft and the first shaft. The communicating parts are defined at a position in the upper side of the first shaft and at a position between the second shaft and the first shaft. The air breather chamber communicates with open air via the air communicating hole, and communicates with an inside part of a casing assembly via each of the communicating parts.
