Claims

[Scope of Utility Model Registration Claim] A select return device provided on the ball part of the shift lever, which is arranged so as to be rotatable around the axis of the shift lever on the ball part, and has a cam at each end in the rotation direction. a select plate in which a sloped portion having a surface is formed and a V-shaped sloped portion is formed on a surface perpendicular to the meridian of the sphere at approximately the center in the rotational direction; and a cam surface of the sloped portion when the shift lever is operated to select. a pin member that rotates the select plate around the axis of the shift lever by pressing in the direction of the sphere meridian;
an upper plate disposed on the sphere on the side opposite to the select plate surface on which the V-shaped inclined portion is formed; and an urging member that urges the upper plate toward the select plate in the meridian direction of the sphere. , is arranged between the V-shaped inclined part and the upper plate, and when the select plate is rotated by the select operation, the V-shaped inclined part is moved in the direction of the sphere meridian by the pressing force from the upper plate. A select return device for a manual transmission, comprising: a rolling member that presses the select plate to return the select plate to its pre-rotation position.
