Abstract: In a variable intake apparatus for an internal combustion engine, each of a plurality of intake pipes (1) is separated from a surge tank (2) by a partition wall (3), and communication ports (31), provided in the partition wall (3) for the respective intake pipes (1), are opened and closed by respective variable intake valves (4) to adjust length of intake passages. In a valve housing (41) that retains the variable intake valves (4), a first rib (45) is formed in an area between each pair of the variable intake valves (4), in which a turning shaft (5a; 5b) is disposed and inserted. The first rib (45) is formed in parallel with the turning shaft (5a; 5b). The valve housing (41) includes a fastening portion (47) that is used to fasten the valve housing (41) to an upper cover (C) with a bolt (41a). A second rib (46) is formed in an area that is close to one of the communication ports (31) that is close to the fastening portion (47).
