A manual transmission shifting device for an automobile comprising:

• a casing;
• a shift lever being retained rotatably with respect to said casing;
• a cam member comprising a cam face, and interlocking with said shift lever to swing, when said shift lever swings in selecting directions;
• a retaining member being fixed so as to be swingable relative to said shift lever and said cam member;
• a locking ball pin comprising a rotatable roller interlocking with said shift lever to come into contact with said cam face, a body unit retaining said roller rotatably, and an expandable and contractible spring being fixed with respect to said retaining member at one of opposite ends and with respect to said body unit at the other one of the opposite ends;
• and
• a damper inhibiting said spring from expanding and contracting,
• wherein said damper is fixed with respect to one of said retaining member and said locking ball pin on one side of said damper in expanding and contracting directions, and a clearance is disposed between the other one of said retaining member and said locking ball pin on the other side of said damper at a time of neutral when any one of a plurality of change-speed stages is not selected in the automobile,
• when said shift lever swings in said selecting directions, said shift lever moves among a position at said time of neutral, a position of LOW on a left side of said position at said time of neutral, a position of HIGH on a right side of said position at said time of neutral and a position of reverse on a left side of said position of LOW, and
• a size of said clearance is larger than zero in a range from said position at said time of neutral to said position of LOW and said position of HIGH and is zero in a range closer therefrom to said position of reverse.
