To provide a bicycle parking device which makes use of energizing force of a gas spring more efficiently than ever.

The bicycle parking device is formed of a support 1, a support groove member 2, a stand 3, an intermediate member 4, a force application member 5, and the gas spring 6. The intermediate member 4 is arranged in the support groove member 2 at a grooved internal rear portion and at a location under the stand, and has a front portion thereof engage with an engaging means 7 of the stand 3 when the stand 3 is drawn out, and a rear portion thereof depressed by the stand 3. Further the intermediate member 4 has an elliptic hole formed in a side surface thereof, in which a fixing member 8 arranged on the support groove member 2 makes an apparent upward movement along a circular arc around a rear end of the support groove member 2. Then the force application member 5 has a rear portion thereof rotatably attached to the rear portion of the intermediate member 4, and is formed like the ell so as to apply a force almost perpendicular to a tilting surface of the intermediate member 4, from the intermediate member 4 to the stand 3. Furthermore the gas spring 6 is arranged on a rear portion and a lower surface of the support groove member 2, and allows a front portion of the force application member 5 to be rotatably attached to the rear portion thereof, and applies a force to the front portion of the force application member 5 in a direction that is directed to the rear of the support groove member 2.
