A foldable parking rack for a bicycle, the foldable parking rack comprising:

• a base having a wheel receiving frame, which has two elongated limiting members and two abutting members attached to two ends of each of the two elongated limiting members respectively and concaved at middle parts thereof with two abutting recesses respectively, and a first connector, an end of which is attached to an outer end of one of the abutting members, an accommodating space being formed between the two elongated limiting members and between the two abutting members;
• and
• a limiting device having a swinging bar provided at an end thereof with a second connector, two limiting cones, each of which has a peak and a bottom, a pivot inserted through the first connector and the second connector, and a spring sleeved onto the pivot, the two limiting cones being installed at another end of the swinging bar in a way that the peaks of the two limiting cones are pointed towards each other and the bottoms of the two limiting cones are located by two sides of the swinging bar respectively,
• wherein when the swinging bar is swung about the pivot, a body of the swinging bar is swung correspondingly to the accommodating space and the two abutting recesses in a way that a juncture of the peaks of the two limiting cones corresponds to the accommodating space and the two abutting recesses;
• the spring provides the swinging bar a restoring elastic force after the swinging bar is swung,
• wherein when the swinging bar is swung about the pivot, the body of the swinging bar is swung between two imaginary vertical planes, in which the two elongated limiting members are respectively situated, and
• wherein the body of the swinging bar is in alignment with a juncture of the peaks of the two limiting cones.
