  • Patent number: 11226036
    Abstract: A shift lever device is provided with retention frames at a front side and rear side of a lever, and a plate is provided with blocks at the front side and rear side of the lever. Even if the plate and the lever are installed to a vehicle with the front side and rear side of the plate and the lever reversed, changing the retention frame that retains a detent rod enables the block on the side of the detent rod to restrict swinging of the detent rod, enabling swinging of the lever to be restricted. This thereby enables the plate and the lever to be commonly employed.
