PROBLEM TO BE SOLVED: To provide a partition member that vertically divides inside a water jacket of an internal combustion engine cylinder block, for being precisely arranged at a desirable position, and closely contacting an edge of the member to an inner wall of the water jacket.

SOLUTION: A spacer 4 contacts a bottom surface 10b of the water jacket 10 so that a vertical position of the flow passage partition member 6 is precisely determined. A size in a width direction of the flow passage partition member 6 is reduced by elastic deformation when inserted into the water jacket 10 so that the flow passage partition member 6 can be arranged in the water jacket 10. After arranged, the flow passage partition member 6 can closely contact the inner wall of the water jacket 10 in the width direction by an elastic restoring force thereof. Upward shifting of the water jacket 10 is prevented by the close contact. As the problem is solved in this way, cooling water above and below the flow passage partition member 6 is prevented from being easily exchanged, thereby sufficiently effecting cooling of the cooling water with different flow rates in the vertically-divided sections above and below the flow passage partition member 6, and effectively decreasing a temperature difference of a cylinder bore portions 12 in the vertical direction.

【課題】内燃機関シリンダブロックのウォータジャケット内を上下に分ける部材を所望の位置に正確に配置でき、縁をウォータジャケットの内壁に密着できる区画部材。
【解決手段】スペーサ4がウォータジャケット10の底面10bに当接することで流路分離部材6の上下位置が正確に決定される。流路分離部材6はウォータジャケット10への挿入時に弾性変形により幅方向のサイズが小さくなることでウォータジャケット10内に配置できる。配置後はその弾性復元力により幅方向にてウォータジャケット10の内壁に密着できる。この密着によりウォータジャケット10の上方への移動も阻止される。このように課題が達成されると、流路分離部材6の上下で冷却水が容易に入れ替わるのが防止されるので、流路分離部材6の上下にて流量を分けて冷却する効果が十分に発揮できるようになり、シリンダボア部12の上下方向での温度差を効果的に減少できる。
