  "textContent": "A rotary wheel cap includes a fixed base (10) fixed to a center (41) of a wheel (40), a rotary cover (20) axially mounted onto the fixed base (10), and an elastic member (30) installed between the fixed base (10) and rotary cover (20). When the wheel (40) rotates, the rotary cover (20) compresses the elastic member (30) to a first position to form a positioning relationship with the fixed base (10), such that the rotary cover (20) is rotated with the wheel (40) and fixed base (10) at the first position. When the wheel (40) is still, the rotary cover (20) is supported by the elastic member (30) at a second position to release the positioning relationship with the fixed base (10). The rotary cover (20) is rotated axially with respect to the fixed base (10) by gravitation of a weight balancing portion (27) at the second position. A design pattern (26) on the rotary cover (20) is aligned correctly by the axial rotation of the rotary cover (20) when the wheel (40) is still.",
