Patent ID: 7404451

Claim:
A hand-held power tool, comprising: a spindle ( 8 ); and a wobble device ( 20 ) for imparting a reciprocating movement to the spindle ( 8 ), the wobble device including: a drive member ( 22 ) rotatable about a drive axis (A); a driven member ( 26 ) oscillatingly pivotable about a wobble axis (T) and connectable with the spindle ( 8 ); and a wobble bearing ( 30 ) for connecting the driven member ( 26 ) with the drive member ( 22 ), wherein the wobble bearing ( 30 ) has a drive-side bearing region with a drive-side guide ( 34 ) circumferentially arranged about the drive axis (A) and provided on the drive member ( 22 ), a driven-side bearing region with a driven-side guide ( 38 ) circumferentially arranged about the drive axis (A) and provided on the driven member ( 26 ); and roll elements ( 28 ) guided simultaneously in both guides ( 34 , 38 ), and wherein the wobble bearing ( 30 ) has, in one of the bearing regions, on a first side ( 46 , 48 ; 50 , 52 ) of the one region, with respect to an associated guide ( 34 ; 38 ), a reinforced cross-section in comparison with a second side ( 48 , 46 ; 52 , 50 ) of the one region, and wherein the one bearing region is the driven-side bearing region, and wherein the reinforced cross-section is produced-by decreasing an inner diameter (IDV: IDV 1 ) of the first side ( 48 ; 46 ) of the driven-side bearing region on the driven-side guide ( 38 ) relative to the second side ( 46 , 48 ) of the driven-side bearing region.
