Joint mechanism for mowing machine

摘要

The invention provides a joint mechanism for a mowing machine which can easily be assembled and disassembled. A support member 1a of a casing 1 houses a cylindrical damper 3 which prevents vibration of a power unit A from being transmitted to a rod 10, a holder 2 to which the rod 10 is inserted and a clamp 4 which prevents the damper 3 and the holder 2 from falling off the support member 1a being inserted therein. The clamp 4 has flexible arms 4a which extend in the direction of an output shaft 11 of the power unit A, while an engagement hook 4b is formed on the tip of the arm 4a and an engagement hole 1b to which the engagement hook 4b of the clamp engages is provided on the support member 1a.
