  "textContent": "A valve characteristic changing apparatus for an internal combustion engine according to the invention is provided with an intake-side variable valve timing mechanism (30) that changes a valve timing of an intake valve of an internal combustion engine (10), and an exhaust-side variable valve timing mechanism (40) that changes a valve timing of an exhaust valve. The intake-side variable valve timing mechanism (30) is a mechanism that uses an storage battery (22) as a power source; the exhaust-side variable valve timing mechanism (40) is a mechanism that uses a hydraulic pump (20) of an engine driving type as a power source.",
