ABSTRACT:
To provide a pivotal structure of an oscillating member facilitating management of parts and fixing work. The cylindrical peripheral face (11A) of a collar (11), which is fixedly secured by screwing a bolt (4) being inserted in a bolt insertion hole (11C ) into a tapped hole (13) in a fixed part (12), is rotatably fitted in a bearing hole (9) bored in a pivot guide portion (6) provided on the side of the pivotal support end of an oscillating member and, by means of collar movement restricting faces (8A, 10A) at the pivot guide portion (6), the cylindrical peripheral face (11A) is prevented from coming off the bearing hole (9). Since, the collar (11) is previously incorporated in the pivot guide portion (6) before the oscillating member is secured to the fixed part (12) and such assemblies can be arranged as a set of parts, management of parts and fixing work are made easier.
