A start control apparatus which is applied to a hybrid vehicle, the hybrid vehicle including: a manual transmission having plural shift stages where different gear ratios from each other are set respectively, the shift stages being changed from each other in response to an operation of a shift lever; a rotating member being connected with an input shaft of the manual transmission via a first clutch to be actuated in response to a stepping operation of a clutch pedal; an electric motor being provided so as to be allowed to transmit power to the rotating member; and an internal combustion engine being connected with the rotating member so as to be allowed to transmit power via a second clutch, wherein the start control apparatus includes a control device which controls operations of the electric motor, the internal combustion engine, and the second clutch, the control device makes the vehicle start off by using power of at least any one of the internal combustion engine and the electric motor when predetermined start conditions are satisfied, the start conditions include that: the second clutch is in a release state where power transmission between the internal combustion engine and the rotating member is shut off; the first clutch is in an engaged state where power is transmitted between the rotating member and the input shaft of the manual transmission; and an accelerator opening of the vehicle is greater than zero, the second clutch is a friction clutch, and the control device, when the vehicle is made to start off by the internal combustion engine, switches gradually the state of the second clutch from the release state, to an engaged state where power is transmitted between the internal combustion engine and the rotating member while increasing gradually output power of the internal combustion engine, after the predetermined start conditions are satisfied. a manual transmission having plural shift stages where different gear ratios from each other are set respectively, the shift stages being changed from each other in response to an operation of a shift lever; a rotating member being connected with an input shaft of the manual transmission via a first clutch to be actuated in response to a stepping operation of a clutch pedal; an electric motor being provided so as to be allowed to transmit power to the rotating member; and an internal combustion engine being connected with the rotating member so as to be allowed to transmit power via a second clutch, wherein the start control apparatus includes a control device which controls operations of the electric motor, the internal combustion engine, and the second clutch, the control device makes the vehicle start off by using power of at least any one of the internal combustion engine and the electric motor when predetermined start conditions are satisfied, the start conditions include that: the second clutch is in a release state where power transmission between the internal combustion engine and the rotating member is shut off; the first clutch is in an engaged state where power is transmitted between the rotating member and the input shaft of the manual transmission; and an accelerator opening of the vehicle is greater than zero, the second clutch is a friction clutch, and the control device, when the vehicle is made to start off by the internal combustion engine, switches gradually the state of the second clutch from the release state, to an engaged state where power is transmitted between the internal combustion engine and the rotating member while increasing gradually output power of the internal combustion engine, after the predetermined start conditions are satisfied.
