Further, the grounding leg (4) (4) developed in a V-shaped state is locked by the engaging surface (34) (34) under the main block portion (35) of the slider (3), and is kept in a state of being unfolded. Further, an upper portion of the side wall of the main block portion (35) of the slider (3) is drilled for receiving the positioning pin (8) and elastically pushing the positioning pin (8) toward the positioning hole (22) and the retaining piece 11 1379786 The positioning pin receiving hole (33) of the spring (7) is urged in the direction of the hole (23). Further, the front end of the grounding leg (4) is provided with a sleeve (5) made of rubber or the like which prevents the holder (1) from sliding left and right to the ground. Fig. 5 is a perspective view showing the state in which the holder (1) of the present embodiment is detached from the bicycle and is folded and stored when the belt is carried. When the state of use of the second figure is to be folded into the folded state of the fifth figure, first, the grounding legs (4) of the two front ends that are opposite to each other are folded inwardly (the front end is in the direction of closing) Then, while pushing the positioning pin (8), push the grounding leg (4) upward until the positioning pin (8) is inserted into the body post (2) by the force of the spring (7). In the meantime, the grounding leg (4) is folded and housed in the body pillar (2), and is folded. That is, the bicycle support is folded to be approximately the same size as the main body support (2) and is convenient to carry. When the bicycle support of the above embodiment is to be used, as shown in the first figure, the crank (10) on one side of the bicycle is first rotated to a substantially downward posture. Next, the pair of grounding legs (4) (4) are pulled out from the opposite end of the pedal shaft insertion slot (21) of the body pillar (2), specifically, the positioning pin (8) is first pressed into the stop hole. After (23), slide the slider (3) to the direction in which the grounding leg (4) (4) is pulled out, and the triangular column-shaped grounding leg mounting portion (30) protruding from the slider (3) slides out. End portions of the body pillars (2), and then each grounding leg (4) is pivoted by a portion of the fixing screw (6), and each grounding leg (4) (4) is pivotally connected to the ground at one end In the state in which the leg attachment portion (30) is in the direction in which the other end faces away from each other, the front end is opened (the state of the second figure). Then, the pedal shaft formed on the body strut (2) is inserted into the opening end of the slot (21), and the end of the pedal 12 is aligned with the base end of the pedal tower i), and in this state, the body pillar (7) " The lower end portion of the crank (1G) is slid rearward, so that the main body column (2) can be attached to the crank (10) with the pedal shaft insertion slot (21) from the outer sleeve pedal shaft (9). In this state, as shown in Fig. 1, the grounding leg (4) (4) can be deployed to the side of the bicycle to open the grounding foot (4) (4) to the ground, so that the bicycle can be stopped. . In this parking state, the bicycle support is attached to the front end of the crank (1〇) closest to the ground. Therefore, the entire size of the bicycle support can be shortened to reduce the size and weight. The use of the support (1) of the present invention can be widely utilized for bicycles or race off-road vehicles used for road races, or various bicycles that are limited by the structure of the vehicle body and cannot be mounted.
