Abstract:
1. A mounting structure of a drive-shaft which transmits a driving force of a transmission to a wheel, comprising: a shaft including a first end operably connected to a transmission and a second end operably connected to a driven wheel; a housing operably coupling the first end of the shaft to the transmission; a spring guide slidably disposed inside the housing, including an end facing the first end of the shaft; and a spring with one end supported by the spring guide and another end supported by the housing, wherein the transmission has a companion flange including a cup-shaped coupling portion, so when the housing enters the coupling portion, with the shaft operably coupled with the driven wheel, an elastic force of the spring biases the housing into the coupling portion, and wherein spherical surfaces that protrude toward each other are formed at the end of the spring guide which faces the shaft and the first end of the shaft which faces the spring guide, respectively.
