Move 8 to 8 df. In the low rotation range, the movable tubes 8a to 8d are moved in the direction of extension from the fixed tubes 53 to 5d, thereby increasing the total length of the intake passages 203 to 20d extending from the upstream end of the movable tubes 83 to 8d to the cylinder 3. Conversely, in the commercial rotation range, the movable tubes 8a to 8d are recessed into the fixed tubes 53 to 5d,
As a result, the total length of the intake passages 208 to 20d from the upstream ends of the movable pipes 8a to 8d to the cylinder 31 is shortened.
