The elastic member can be held firmly, and the massive elastic member is hollow
Inconvenient situation such as getting out of the unit and causing malfunction
Can be eliminated, and the pressing body is
A hollow member is formed from a low friction material.
And the massive elastic member fits into the hollow part of the hollow member
Of the pair of bevel gears
There is no difficulty in turning, and wear of the hollow member can be reduced.
As described above , the pressing force can be evenly applied to the pair of bevel gears.
