The invention relates to a selection operation device for a manual transmission and discloses a selection operation device for a manual transmission. The device is applied to a control mechanism for selecting the operation among an overall four-stage gear selection range, wherein the operation sense is kept the same during the displacement selection within a gear shifting selecting interval. The selection operation device for the manual transmission comprises a selection spring (20) and a pawl mechanism. The selection spring (20) is contracted respectively from an initial first-stage gear selecting interval on one side of a selection neutral position (N) to a second-stage gear selecting interval on the other side thereof after the first stage. The pawl mechanism is contracted from the selection neutral position (N) towards the first-stage gear selecting interval on the other side thereof.
