내연 기관의 기관 압축비를 변경 가능한 가변 압축비 기구(20)를 구비하고, 현재의 기관 압축비의 상태를 표시하는 표시부(41)를 마련한다. 이 표시부(41)는, 최고 압축비를 포함하는 최고 압축비의 근방과, 최저 압축비를 포함하는 최저 압축비의 근방 중 적어도 한쪽에서, 기관 압축비의 변화에 대하여 표시가 변화되지 않거나, 혹은 표시의 변화가 작은 불감대부(51, 52)를 갖는다. 운전자에게 기관 압축비의 상태를 표시함으로써, 운전자에게 기관 압축비의 상태를 인식시킬 수 있다. 또한, 불감대부(51, 52)를 마련함으로써, 최고 압축비 또는 최저 압축비의 근방에서, 기관 압축비의 표시는 부주의하게 변화되는 일이 없어, 운전자에게 위화감을 주는 것을 억제할 수 있다. The invention is provided with a display unit (41) for displaying the state of the current engine compression ratio, said unit (41) being used in a vehicle provided with a variable compression ratio mechanism (20) with which it is possible to change the engine compression ratio. The display unit (41) has dead zones (51, 52) in which the display does not change or changes only slightly in relation to changes in the engine compression ratio in the vicinity of a maximum compression ratio that includes the maximum compression ratio, and/or in the vicinity of a minimum compression ratio that includes the minimum compression ratio. The state of the engine compression ratio is displayed to the driver to allow the driver to be aware of the state of the engine compression ratio. Also, providing the dead zones prevents the display of the engine compression ratio from undergoing abrupt changes in the vicinity of the maximum compression ratio, and makes it possible to inhibit driver discomfort.
