Abstract
An air intake device for an internal combustion engine includes an air intake path, a throttle valve, and a first partition plate. The throttle valve is provided in the air intake path and includes a valve shaft and a valve body. The valve body is connected to the valve shaft to open and close the air intake path and has a first end and a second end. The first partition plate is disposed approximately parallel to a flow direction of intake air and includes opposite ends connected to a first inner wall surface of the air intake path closer to the first end than the second end. The first partition plate has a substantially curved convex shape protruding radially inward of the air intake path. The first partition plate is located downstream of the first end of the valve body.
