A truckle assembly has a housing (1), a rotating unit (2) movably mounted on the housing, a limiting unit (3) and a wheel assembly (4). The housing includes a body (10) and a sleeve (11). A slope portion (13) is formed inside the body and neighboring the sleeve. The rotating unit includes a central shaft (21), and a gear ring (22) mounted on the central shaft for corresponding to a first side of the slope portion. The limiting unit includes a pedal (31), an interferential portion (32) linking an end of the pedal, and an arresting portion (33) linking an end of the interferential portion. The pedal has a first portion extending into the housing, and a second portion extending out of the housing. The interferential portion corresponds to a second side of the slope portion. The wheel assembly includes at least a wheel (4) assembled on sides of the housing, and a shaft pole (42) extending through the wheels and the pedal.
