<p>An engine intake device wherein the joining surface (11a) of a device block (11) is connected to the attaching surface (10a) of a throttle body (1) parallel to an intake way (2), and a bypass passageway (15) is composed of a bypass inlet hole (20) establishing communication between the upstream region of the intake way (2) and an attaching surface (1a), a bypass outlet hole (21) establishing communication between the downstream region of the intake way (2) and the attaching surface (1a), an upstream groove (16) formed in the joining surface (11a), a downstream groove (17) formed in the joining surface (11a), and a valve chamber (22) establishing communication between the upstream and downstream grooves ( 16, 17), and wherein a bypass valve (25) and an actuator (28) therefor that face the valve chamber (22) are arranged in the device block (11) to be parallel to the joining surface (11a), and a throttle sensor (8) is arranged in the device block (11). This makes it possible to improve workability and assembly while reducing the size of an engine intake device having a bypass valve and an actuator therefor.</p> |
