A torque limiter includes a first meshing portion provided at a surface of an input shaft, a plate including a second meshing portion which is configured to mesh with the first meshing portion, and a disc spring portion integrally rotatable with an output shaft. The disc spring portion includes an engaging portion engaging with the plate. The disc spring portion is deflected to displace the engaging portion in a direction opposite to the plate in a case where a load equal to or greater than a set value is applied to the disc spring portion while pressing the plate via the engaging portion so as to bias the second meshing portion towards the first meshing portion.

A drive apparatus for a hybrid vehicle includes: an engine applying a drive force to drive wheels via a drive shaft; a motor applying a drive force to the drive wheels via a rotation shaft; a planetary gear mechanism having first, second, and third elements lining up sequentially with a gap interposed therebetween corresponding to a gear ratio; and an automatic transmission having input and output shafts rotatably connected to the drive wheels, and changing a gear ratio obtained by the division of the rotation speed of the input shaft by the rotation speed of the output shaft, wherein the input and drive shafts are connected to the second element, the output shaft and one end of the rotation shaft are connected to the first element, and the output shaft and the other end of the rotation shaft are connected to the third element.
