ECCENTRIC VARIABLE ADJUSTING DEVICE FOR ECCENTRIC WHEEL

Japanese Patent JP3276843

B2

PROBLEM TO BE SOLVED: To facilitate the adjustment of eccentricity by providing an eccentric cam member, which is formed of an eccentric cam and a locking wheel, an eccentric cam member, which is formed of an eccentric cam and a flange part, a stopper body of a locking part to be engaged with the locking wheel, and a manual operating means, which releases the engagement, resisting the energizing force.
SOLUTION: An eccentric cam member 3 to be loosely fitted to an eccentric cam 2a of an eccentric cam member 2 of a spindle 1 has an eccentric cam 3b and a flange part 3c, and a groove 3d is provided on the circumference of the flange part 3c, and a recessed groove 3e is provided in a side surface, and a locking part 10a to be engaged with a locking wheel 2b is provided in a stopper body 10 to be slid for fitting in the recessed groove 3e. The stopper body 10 is pinched by the eccentric cam member 2 and the eccentric cam member 3, and in ordinary, the locking wheel 2b and the locking part 10a of the stopper 10 are engaged with each other by a torsion spring 13 of the eccentric cam member 3 so that the eccentric cam member 3 is turned with the spindle 1 integrally. A manual operating body 17 is pushed, resisting a coil spring 18, so as to separate the locking part 10a and the locking wheel 2b from each other, and engaged with the groove 3d, and the eccentric cam member 3 is fixed, and the eccentric variable is adjusted by the rotation of the spindle 1. Adjustment of the eccentric variable is thereby facilitated.
