徴とする歯車式変速機のミスシフト防止装置。[Claim for Utility Model Registration] Select operation is performed by axial displacement of the control rod, shift operation is performed by rotation around the axis, and the reverse gear and the predetermined forward gear are intermediate positions corresponding to the neutral position. In a gear type transmission set to opposite shift positions, an engaging portion is provided at one end of the control rod, and when the control rod is operated to select between the reverse gear and a predetermined forward gear. When the control rod is moved in the axial direction and the control rod is shifted to a predetermined forward gear side, the control rod includes a cam member provided at one end with a first cam portion that engages with the engaging portion so as to move around the shaft. A stopper member is disposed coaxially with the cam member and prevents the second cam portion provided at the other end of the cam member from rotating when the control rod is rotated from a predetermined forward speed through an intermediate position to a reverse speed side. The cam member is provided with a spring that allows axial displacement of the cam member to maintain the cam member at a neutral phase at all times, and also provides a spring that biases the control rod in the axial direction. A misshift prevention device for a gear type transmission, characterized in that a direct shift operation to a reverse gear is prohibited.
