A propelling equipment has an engine, a first motor/generator, a second motor/generator and a planetary gear train. A common velocity diagrammatic view has at least four members. One of the rotational members corresponds to a second member, one of the rotational members corresponding to a third member, and one of the rotational members corresponding to a fourth member connected with the second motor/generator. One of the second member and the fourth member corresponds to a low-seed step fixed ratio member, a fixed transmission ratio at a low-speed step being obtained by fixing the low-seed step fixed ratio member on a stationary part of a case. The fourth member is fixable to the stationary part when the first member is fixed or rotates at a low speed to obtain a speed increasing transmission ratio.
