CONNECTING STRUCTURAL BODY OF HOSE

摘要

PROBLEM TO BE SOLVED: To provide a connecting structural body of a hose 20 capable of preventing sealability from lowering with lapse of time and facilitating connection operation. SOLUTION: This connecting structural body for the hose 20 comprises a mounting block 24 having an installation hole 25a connected to a passage 25b and a locking member 28. The locking member 28 comprises a locking side engaging part 28b engaged with a bellows part 21. The bellows part 21 inserted into the installation hole 25a is compressed in longitudinally direction through the locking side engaging part 28b so as to install the hose 20 in the installation hole 25a in the state of being sealed in the passage 25b. The locking side engaging part 28b is provided so as to be locked to the bellows part 21 at five positions equally spaced in the circumferential direction of the bellows part 21.
