The present disclosure provides a brake mechanism (10) of a cart, a drive member (100) of the brake mechanism (10), a pedal structure (A100), a wheel structure (A1), and a cart, wherein the drive member (100) is arranged in the brake mechanism (10) to be movable between a locking position and an unlocking position, such that the brake mechanism (10) locks or unlocks a wheel (1) of the cart, wherein the drive member (100) has a guiding side face (110), and the guiding side face (110) is provided with a guiding slot (120) including a stop slot (123); wherein the brake mechanism (10) is also provided with a braking member (200), a stop end (210) of the braking member (200) is arranged to move in the guiding slot (120), and by moving the drive member (100) to the locking position toward the locking direction, the stop end (210) moves in the guiding slot (120) to the stop slot (123) along a first direction and stays at the stop slot (123); wherein the drive member (100) is provided with an anti-damage device, and the anti-damage device is arranged such that when a user tends to move the drive member (100) in an incorrect direction, the anti-damage device is able to elastically obstruct or prevent the stop end (210) from moving away from the stop slot (123) in the first direction. According to the disclosure, even if the user accidentally performs a misoperation during the process of unlocking, the drive member (100) can still return to the unlocking position to unlock the wheel (1).
