Claim 0:
1. An engine intake structure for vehicles, comprising:
an intake passage member which defines an intake passage for supplying air to an internal combustion engine, and which also defines a resonator chamber in communication with the intake passage; and
an in-vehicle device located in an engine room of a vehicle, the in-vehicle device having a preset reference temperature for temperature control,
wherein the intake passage member is located above and adjacent to the in-vehicle device,
wherein the intake passage extends above the in-vehicle device so as to at least partially overlap the resonator chamber as viewed in a vertical direction,
wherein the intake passage member comprises:
a lower member forming a bottom wall of the resonator chamber and located adjacent to the in-vehicle device;
a middle member including a portion forming an upper wall of the resonator chamber and a bottom wall of the intake passage, the middle member being coupled to a top of the lower member; and
an upper member including a portion forming an upper wall of the intake passage, the upper member being coupled to a top of the middle member,

wherein the resonator chamber includes a first resonator chamber and a second resonator chamber, the second resonator chamber being smaller than the first resonator chamber,
wherein the engine intake structure further comprises a first communication passage in communication with the first resonator chamber; and a second communication passage in communication with the second resonator chamber,
wherein the first and second communication passages are communicably connected to the intake passage at respective locations which are spaced apart from each other in an axial direction of the intake passage, and
wherein the first and second communication passages are defined by the upper member and the middle member and extend along joining surfaces of the upper member and the middle member to each other, and the first communication passage includes a portion extending in the axial direction of the intake passage.
