<P>PROBLEM TO BE SOLVED: To provide a drive plate and a ring gear member of drive plate, capable of reducing an effect of heat due to welding to a ring gear and more appropriately securing durability of a connection part of a drive plate to a power transmission object. <P>SOLUTION: The drive plate 10 includes: a plate member 11 fixed to a crankshaft 2 of an engine; and a ring gear member 12 which has a ring gear 120 on the outer circumference and has a plurality of fastening parts 121a fastened to the plate member 11 on the inner peripheral side than the ring gear 120. Therein, the ring gear member 12 is extended respectively from the inner peripheral side than the ring gear 120 to a fluid transmission device 3 side and includes a plurality of extension welding parts 122 having circumferential part 122a welded to a front cover 30 of the fluid transmission device 3. Further, a rib part 123 having a height lower than both neighboring extension welding parts 122 is formed so as to continue with both neighboring extension welding parts 122 between the extension welding parts 122 adjoining each other of the ring gear member 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
