Document Type and Number:
Japanese Patent JP2023135277
Kind Code:
A
Abstract:
To disclose a structure capable of performing connection without straining and improving sealability, in a pipe one end of which is inserted into a connection port and in which a bracket is fixed to a bolt.SOLUTION: A sealing material (O-ring 18) is mounted to one end part 15a of a cooling water return pipe 15. A hose 16 is connected to the other end part 15b of the cooling water return pipe 15. A first bracket 24 and a second bracket 25 facing in opposite directions are fixed to the cooling water return pipe 15, and the second bracket 25 is fixed to a cylinder block 1 with a bolt 35. When the cooling water return pipe 15 is inserted into a connection port 13, a cut groove 26 provided in the first bracket 24 is fitted into a receiving member (stud bolt 27) protruding from a cylinder head 2. Consequently, the posture of the cooling water return pipe 15 is maintained. The stud bolt 27 also functions as a rotation stopper when fixing another member 28 with a bolt 29.SELECTED DRAWING: Figure 2
