摘要：A brake device for a pushcart includes a rotary lever rotatable on a basebetween first and second positions and biased to the first position. A cam member isrotatable within the rotary lever, and has a convex portion and a concave portion. Abraking pin is disposed movably on the base, and is biased to contact the cam member.
When the rotary lever is rotated from the first position to the second position, the cammember rotates so as to move an end of the braking pin from one of the concave portionand the convex portion onto the other one of the concave portion and the convexportion, thereby switching the braking pin between a braking position and a releaseposition.
