<P>PROBLEM TO BE SOLVED: To provide a gear part-fitting structure suppressing decline in feeling of handle manipulation by a fisherman. <P>SOLUTION: The gear part-fitting structure comprises a screw shaft 16 of an oscillating mechanism 6, an intermediate gear 18 and a circular component 20. In this structure, the screw shaft 16 comprises a fitting element 16c provided on one side end of a shaft body 16b, an engagement element 16d formed with a small diameter on th tip of the fitting element 16c and so designed that the axial sectional shape be noncircular, and a groove 16e recessedly formed along the outer circumference of the basal end of the fitting element 16c and to be fitted with the circular component 20. The intermediate gear 18 comprises a recessed element 18c recessedly formed on the inner circumferential side of a gear body 18a and to be fitted with the fitting element 16c in a relatively unturnable way, and a recessed element 18d formed communicatingly so as to represent a small diameter on the tip side of the recessed element 18c and to be engaged with the engagement element 16d. The circular component 20 is an elastomeric O-ring interposed in between the fitting element 16c and the recessed element 18c. <P>COPYRIGHT: (C)2007,JPO&INPIT |
