    • 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).
    • 在用于内燃机的可变进气装置中,多个进气管道(1)中的每一个通过分隔壁(3)与缓冲罐(2)分离,并且设置在分隔壁 (3)分别由相应的可变进气门(4)打开和关闭,以调节进气通道的长度。 在保持可变进气门(4)的阀壳体(41)中,在每对可变进气门(4)之间的区域中形成有第一肋(45),转向轴(5a; 5b) 被设置和插入。 第一肋(45)与转动轴(5a; 5b)平行地形成。 阀壳体(41)包括用于通过螺栓(41a)将阀壳体(41)紧固到上盖(C)的紧固部分(47)。 第二肋(46)形成在靠近紧固部(47)的一个连通口(31)的区域中。
