At the same time, the pins 5 and 5 are fitted in a retractable manner, and the retainers 6 and 6 in which the pins 5 and 5 are fitted to the brackets 1 and 1 facing the both end surfaces of the boss 2 have the tips of the retainers 6 and 6. Sealing member 7,7
It is also known that the shims 8 and 8 are brought into contact with the bracket 1 and fixed to the bracket 1, and further the fitting 10 is provided in the middle portion of the boss 2 for lubricating. Although it is slightly easier than that shown in FIGS. 4 and 5, there is a problem in strength because the cross-sectional areas of the protrusions formed on both sides of the pin groove for transmitting the moment of the pin cannot be made large. It was
