To provide an intake system capable of suppressing variation of distribution of external gas to four continued cylinders that are a first cylinder, a second cylinder, a third cylinder, and a fourth cylinder.SOLUTION: An intake system 100 includes an intake system body 30 including first to fourth intake passages 21a-21d respectively corresponding to first to fourth cylinders 2a-2d of a multicylinder engine 1 in which an intake stroke is repeated in the first cylinder 2a, the third cylinder 2c, the fourth cylinder 2d, and the second cylinder 2b in this order. The intake system 100 includes: a distribution passage 51 including a first distribution passage 51a connected to the first intake passage 21a and the second intake passage 21b and a second distribution passage 51b connected to the third intake passage 21c and the fourth intake passage 21d; a first partitioning section 81 for partitioning the first distribution passage 51a; and a second partitioning section 82 for partitioning the second distribution passage 51b.SELECTED DRAWING: Figure 2 【課題】４個の連なる第１気筒、第２気筒、第３気筒および第４気筒への外部ガスの分配のばらつきを抑制することが可能な吸気装置を提供する。【解決手段】この吸気装置１００は、第１気筒２ａ、第３気筒２ｃ、第４気筒２ｄおよび第２気筒２ｂの順に吸気行程が繰り返される複数気筒エンジン１の各々の第１〜第４気筒２ａ〜２ｄにそれぞれ対応する第１〜第４吸気通路２１ａ〜２１ｄを含む吸気装置本体３０を備える。また、吸気装置１００は、第１吸気通路２１ａおよび第２吸気通路２１ｂに接続される第１分配通路５１ａと第３吸気通路２１ｃおよび第４吸気通路２１ｄに接続される第２分配通路５１ｂとを含む分配通路５１と、第１分配通路５１ａを仕切る第１仕切り部８１と、第２分配通路５１ｂを仕切る第２仕切り部８２と、を備える。【選択図】図２
