Specific embodiment
As shown in Figures 1 to 5, a kind of case and bag damping wheel includes support base 10, wheel 20 and combines the utility model
Seat 30, wherein：
The support base 10 includes the first bearing 11 and the second bearing 12, and first bearing 11 has a base portion 111, in the base
The front side of portion 111 tilts backwards and is provided with a projection 112, in being nested with a flexible member 113, the flexible member on the projection 112
113 is spring；Extended back in the rear side of base portion 111 and be provided with the first articulated section 114, first articulated section 114 is a pivot connected slot.
