The invention provides a hybrid electric vehicle employing a permanent magnet type dynamo-electric machine (31) structured such that a torque at a time of reverse rotation is greater than a maximum torque output by a dynamo-electric machine (31) when the dynamo-electric machine (31) normally rotates. Further, the present invention provides a hybrid electric vehicle in which a dynamo-electric machine (31) and an engine (30) are connected to a drive shaft (37) in series and no gear for switching between forward and backward movements is provided, wherein there is employed a permanent magnet type dynamo-electric machine (31) structured such that a torque output by the dynamo-electric machine (31) when the hybrid electric vehicle moves backward (the dynamo-electric machine (31) reverse rotates) is greater than a maximum torque output by the dynamo-electric machine (31) when the hybrid electric vehicle moves forward (the dynamo-electric machine (31) normally rotates). In the hybrid electric vehicle employing the permanent magnet type dynamo-electric machine (31) having a stator (1) having a stator iron core (2) around which a stator coil is wound, and a rotor (6) arranged in the stator (1) at a rotational gap (5) and having a plurality of permanent magnets (8) arranged and fixed within a rotor iron core (7) in a peripheral direction, a ratio between a maximum torque output by the dynamo-electric machine (31) when the dynamo-electric machine (31) normally rotates and a torque output by the dynamo-electric machine (31) when reverse rotating establishes a relation 1:1.05-1.2, whereby the torque at the reverse rotation becomes greater.
