LIQUID SEALING TYPE VIBRATION CONTROL DEVICE AND MANUFACTURING METHOD FOR BOTTOM FITTING OF LIQUID SEALING TYPE VIBRATION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a liquid sealing type vibration control device capable of reducing its weight sufficiently and to provide a manufacturing method for a bottom fitting of the liquid sealing type vibration control device.;SOLUTION: This liquid sealing type vibration control device is provided with a first mounting device, a second mounting device, a vibration control basic body, a diaphragm provided on the second mounting device to form a liquid sealing chamber between the vibration control basic body and it, a partitioning body, and an orifice. The second mounting device is composed of a cylindrical fitting and the cup-like bottom fitting 14, which is formed by aluminum alloy. An opening part 50 of the bottom fitting 14 is composed of a first opening part 51 and a second opening part 52 overhanging from an end part 51C on a large diameter side of the first opening part 51. The other end face 53G side of the second opening part 52 protrudes.;COPYRIGHT: (C)2007,JPO&INPIT
