Air intake chamber for saddled vehicle

A saddle-riding type vehicle comprising;

• an engine;
• a supercharger with a discharge port, which is operable to pressurize and supply an intake air to the engine;
• a throttle body configured to control the amount of intake air to be supplied to an air intake port of the engine;
• an air intake chamber disposed downstream of the discharge port of the supercharger and upstream of the throttle body, wherein the air intake chamber comprises:
• a confronting portion of the air intake chamber having an outlet of the air intake chamber and overlapping the throttle body, the confronting portion defining an interior space of a portion above the throttle body in a direction along an axis of the outlet of the air intake chamber;
• and
• a connecting portion of the air intake chamber to connect the confronting portion and the discharge port of the supercharger, the connecting portion having an outlet side opening that is set to be larger than an inlet side opening, wherein
• the connecting portion has a transverse width that continuously increases from the inlet side opening towards the outlet side opening;
• the air intake chamber is disposed above a cylinder block of the engine, and the supercharger is disposed rearwardly of the cylinder block of the engine and above a crankcase of the engine;
• and
• an intake air duct configured to guide an incoming wind, then flowing forwardly of the engine, towards the supercharger, is disposed to pass laterally of the cylinder block.
