Abstract

The present invention provides an air intake device that can easily install an air filter and an external air pipe in an engine room and ensure sufficient maintenance space. The air intake device of the present invention includes an air filter and an external air pipe. The air filter has: a bottomed cylindrical housing with an open end and an inlet formed therein; and a cover that forms an outflow outlet and will The open end of the housing is blocked; a filter component is present between the housing and the cover, and divides the internal space between the housing and the cover into dustproof areas on the inlet side. and a cleaning part on the outlet side, and the outside air pipe introduces outside air into the air filter, wherein the air filter and the outside air pipe are connected to each other through a fitting pipe, so The fitting pipe has a wall portion constituting the dust-proof portion together with the housing, and the wall portion is assembled in a vertical direction with respect to the inlet.

Description

technical field [0001] The present invention relates to an intake device for an internal combustion engine having an air cleaner for cleaning external air introduced into an internal combustion engine such as an automobile, and an external air pipe connected to the air cleaner to introduce external air. Background technique [0002] Conventionally, various types of air intake devices are known as intake devices having an air cleaner for cleaning outside air introduced into an internal combustion engine and an outside air pipe connected to the air cleaner for introducing outside air. [0003] In addition, in such an air intake device, various structures are known regarding the method of connecting the air cleaner and the external air pipe in consideration of the reduction of the ventilation resistance and the mountability to the vehicle body.
