The insertion shaft 154 is formed hollow so as to insert the shaft of the quick release lever 34 fastened to the front fork 30 of the bicycle and the outer circumferential surfaces of both ends of the quick release lever 34 are formed so as to protrude more than the housing 152 4, grooves 32 formed in the front fork 30 of the bicycle may be formed so as to span both ends of the insertion shaft 154.

After the quick release lever 34 is inserted into the insertion shaft 154 in a state where the front fork 30 and the groove 32 are engaged with each other, the front fork 30 is compressed by pressing the front fork 30, And the insertion shaft 154 can be pressed and fixed.

A urethane bushing 156 may be provided between the insertion shaft 154 and the housing 152. The urethane bushing 156 is formed to have a certain rigidity and elasticity to support a load transmitted through the front fork 30 and the quick release lever 34 and allow a slight clearance.

On the other hand, the present invention is not limited to the quick release lever 34, but other types of shaft members may be used.

5 to 6, the elastic coupling 140 is a constituent element for fixing the end of the swing bar 137 by fixing the end of the swing bar 137, and has a certain degree of elasticity And is a component that imparts a slightly elastic clearance to the swing bar 137.

The elastic coupling 140 may have a hollow cylindrical shape. The first fixing part 142 may be formed on one side of the elastic coupling 140 to which the clamp 136 is fixed. And a second fixing part 144 is formed on the first fixing part 142 and the second fixing part 144. The coil fixing part 144 is formed between the first fixing part 142 and the second fixing part 144, (Not shown).

The coil part 146 of the elastic coupling 140 is formed in a spiral shape and the center of the coil part 146 forming the helical part is connected to the center of the first fixing part 142 and the center of the second fixing part 144, As shown in Fig.

The elastic force of the coil portion 146 can be adjusted by pressing or releasing the coil portion 146.

6, an elastic adjustment bolt insertion hole 148 passing through the coil part 146 is formed parallel to the center axis of the elastic coupling 140, The elastic adjustment bolt 149 can be inserted into the elastic member 148.

At this time, by adjusting the degree of tightening of the elastic adjustment bolt 149, the degree of compression of the coil part 146 can be adjusted and the elastic force can be controlled.

That is, when the elastic adjustment bolt 149 is completely fastened, the coil part 146 is completely pressed and the elastic force is not exerted. When the elastic adjustment bolt 149 is loosely fastened, the coil part 146 is opened, Can be exercised.

Therefore, it is possible to allow elastic clearance to the swing bar 137.

Of course, the elastic coupling 140 is not necessarily fastened to the swing bar 137 and may be provided between the sub-frame 122 and the base 131. The sub- Or the body 102, or may be provided in the center member 104, or in any place where shaft coupling is performed.

The rear wheel support unit 110 is a component coupled to the center member 104 and rotatably supporting the rear wheel of the bicycle.

The rear wheel support unit 110 may include a rotary drum 112, a resistance unit 114, and a freewheel motor 116.

The rotary drum 112 is a component that supports the rear wheel 20 of the bicycle and is rotated by the driving force of the rear wheel.

The resistance unit 114 is a component that adds resistance to the rotary drum 112. In other words, a force that hinders the rotation of the rotary drum 112 is applied through frictional force or electromagnetic force, so that the load can be felt by the user.

The freewheel motor 116 is a component that plays a role opposite to that of the resistor 114 and is a component that adds rotational force to the rotary drum 112. And may be connected to the rotary drum 112 by a gear, a belt, a chain, or the like.

A control unit (not shown) may be provided to control the resistance unit 114, the freewheel motor 116, and the inclination implementation module 130.

The control unit controls the angle formed by the swing bar 137 of the inclination implementing module 130 and the degree to which the resistance force is applied from the resistance unit 114 and the degree of applying the rotational force from the free wheel motor 116 I can do it.

The control unit (not shown) may be controlled by a previously input program or may be controlled by a separate external input signal.

A separate wired or wirelessly connected equipment may be provided for external input of signals to the control unit (not shown), and the equipment may be a computer, a separate console or a smart phone.

In addition, the controller (not shown) may control the inclination implementing module 130 and the rear wheel supporting unit 110 in conjunction with each other.

For example, as shown in FIG. 7, the swing bar 137 of the slope implementing module 130 is raised to increase the resistance of the resistance portion 114 while increasing the front of the bicycle 10, .

Alternatively, as shown in FIG. 8, the swing bar 137 of the inclination implementing module 130 may be lowered so that the front of the bicycle may be lowered. In this state, It is also possible to increase the rotation applying force of the motor 116 as needed to simulate a flat road or a downhill road.

In addition, when the user is pedaling while the front fork 30 of the bicycle is mounted to be coupled to the fork coupling hinge 150, when the pedaling force becomes large, the dancing motion in which the bicycle is tilted to the left and right Lt; / RTI >

This force acts on the front fork 30 coupled to the fork coupling hinge 150 so that when the excessive force is applied to the front fork 30, deformation or breakage may occur. The fork coupling hinge 150 has a resilient urethane bushing Since the elastic coupling 140 is provided on the swing bar 137, a slight elastic clearance can be provided to elastically support the force acting by the dancing motion, and the front fork 30 can be prevented from being damaged or deformed.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
