<p><P>PROBLEM TO BE SOLVED: To provide a device for attaching a grass cutting blade, capable of greatly reducing the time for reversing work in reversing a worn grass cutting blade. <P>SOLUTION: A spring (25) is attached inside a housing (21) and a boss (23) is further fitted into the housing in a rotor (19), wherein both ends of a cylindrical pipe are axially supported, and wherein the cylindrical housing (21) with a through hole a (24) is fused on the circumference of the cylindrical pipe. The boss (23) has a through hole b (26) in a portion located inside the housing (21), and the boss (23) is locked by a pin (22) in such a way as linearly movable and rotatable within the housing (21). The boss (23) also has a holder B (31) in which two plates with through holes c (32) at ends are elected with a certain interval kept in-between in a portion located opposite from a side to be attached to the housing (21), so that the grass cutting blade (15) can be swingably attached. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
