Claims

[Scope of utility model registration request]

A U-shaped engagement body into which a gear shift lever is fitted is fixed to a shifter shaft on which a gear shifter for sliding a gear shifting sliding part is fixed, and two of the retaining bodies are placed facing each other, and a gear shift is performed. In gears that change gears by selective sliding using a lever, a protrusion is provided on the surface of the gear lever in the engaging body selection direction, and when the shift lever is released from the hand after shifting, the protrusion engages with a part of the engaging body on the non-selection side to select the gear. A device for preventing gear pullout, characterized in that the gear on the sliding side is prevented from sliding in the gear pullout direction.
