By aligning the gears, the gear corresponding to the engaged shift guide groove is selected, and one of the pair of shift guide grooves located on the same straight line is used for forward gear selection, and the other is used for selecting reverse gear. In a manual transmission for selection, a reverse gate plate is supported by a support pin to be swingable in the selection direction with respect to the guide plate, and the support pin is attached to one of the guide plate or the reverse gate plate. The reverse gate plate is slidable in the shift direction by forming a penetrating long hole, and when the reverse gate plate is at a predetermined position, the reverse gate plate is located near the intersection of the select guide groove and the pair of shift guide grooves. a pressure receiving part that the selector comes into contact with when the selector in the neutral position is displaced toward the intersection, and a pressure receiving part that the selector in the one shift guide groove is displaced toward the other shift guide groove. and a regulating portion with which the selector comes into contact when the reverse gate plate is moved from the predetermined position to the neutral position by swinging in the select direction and sliding in the shift direction, respectively. The reverse gate plate is configured to move in a direction in which the pressure receiving part is pressed by a selector from the one shift guide groove and in a direction in which the regulating part is pressed by a selector from one of the shift guide grooves, A reverse miss shift prevention mechanism for a manual transmission, characterized in that the mechanism is biased to the predetermined position by a spring and a second spring for biasing in the selection direction. (2) In the scope of the claim for utility model registration, paragraph 1,
The support pin is located closer to the one shift guide groove than the regulating portion located at the predetermined position. (3) In paragraph 2 of the claims for utility model registration,
The elongated hole is located on an extension line of the pair of shift guide grooves. (4) In paragraph 1 of the claims for utility model registration,
The guide plate is formed with a guide surface extending parallel to the pair of shift guide grooves, and the reverse gate plate is provided with a guide surface that is provided with a biasing force of the second spring when the reverse gate plate slides in the shift direction. A contact portion is formed to contact the guide surface. (5) In paragraph 1 of the claims for utility model registration,
The regulating portion is an inclined surface that is inclined toward the one shift guide groove as the second spring is biased.
