PROBLEM TO BE SOLVED: To provide an internal combustion engine cooling mechanism of easy formation making accurate temperature control of a cylinder bore side easy.

SOLUTION: Since a flexible lip member 6 of a partition member 2 is made of elastomer, the same deforms in insertion to a water jacket 12. Consequently, whole body of the partition member 2 can be inserted in the water jacket 12 with guiding the same to a suitable position without receiving large resistant force from an outer circumference surface 14a of the cylinder bore part 14, and an internal combustion engine cooling mechanism can be easily formed. After completion of insertion, the flexible lip member 6 touch the outer circumference surface 14a of the cylinder bore part 14 at a tip edge part 6c thereof by own deformation restoring force, and independency of cooling water flow in a bore side channel 12a and an anti-bore side channel 12b can be sufficiently secured. Consequently, accurate temperature control of the cylinder bore 14b side can be done easily by controlling flow rate of cooling water in each of the channel 12a, 12b.

【課題】シリンダボア側に対する高精度な温度管理を容易とし、形成も容易な内燃機関冷却機構。
【解決手段】区画部材2の可撓性リップ部材6はエラストマーであるため、ウォータジャケット12への挿入時に撓むことで、大きな抵抗力をシリンダボア部14の外周面14aから受けることなく、しかも区画部材2全体を好適な位置に誘導しつつウォータジャケット12内に挿入でき、容易に内燃機関冷却機構が形成できる。挿入完了後においても可撓性リップ部材6は自身の撓み復元力により先端縁部6cがシリンダボア部14の外周面14aに接触し、ボア側流路12aと反ボア側流路12bとの冷却水流の独立性が十分に確保される。このため各流路12a,12bでの冷却水の流量管理をすることでシリンダボア14b側に対する高精度な温度管理が容易なものとなる。
