A guide plate for a shift lever device, which is formed in correspondence with a movement range of a momentary type shift lever that automatically returns to a home position after being operated, is provided with an elastic member that includes an operation hole. The elastic member restricts the movement range of the shift lever and guides movement of the shift lever. An impact absorption mechanism is formed in the elastic member and absorbs impact of the shift lever when the shift lever automatically returns to the home position. The impact absorption mechanism includes a slit arranged proximal to the operation hole. A seat that is capable of absorbing impact of the shift lever is arranged closer to the operation hole than the slit. A stopper arranged at a back side of the seat relative to the slit supports inwardly curved deformation of the seat.
