Title:
DRIVING FORCE TRANSMISSION AND DAMPER DEVICE FURNISHED WITH IT
Document Type and Number:
Japanese Patent JP3927045
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a driving force transmission to display proper blocking force to prevent co-rotation of a driven wheel and not to cause a problem of increase of torque and abrasion in an interlocking territory where the driven wheel is also rotatively driven, and also to provide a damper device furnished with the transmission.
SOLUTION: A can member 8 to integrally rotate with a second driving gear 26 and a disc spring 9 to make contact with a cam surface 81 of the cam member 8 with elasticity are used for the damper device 1. Small diametrical parts 821, 822 and a circular arc part 83 are formed on the cam surface 81, and ridge parts 841, 842 continuously connecting the small diametrical parts 821, 822 and the circular arc part 83 without forming a stepped difference are formed between each of them. Consequently, co-rotation of the second driving gear 26 is blocked by a load generated at the time when a contact position of the cam surface 81 and the disc spring 9 moves to the side of the circular arc part 83 through the ridge parts 841, 842 from the side of the small diametrical parts 821, 822.
