に踏み込んで逆回動させればよい。(Function) In the caster with a brake of the present invention, when the pedal 5 is depressed and one end thereof is rotated in the upward direction, this presses the bulging portion 4a of the elastic plate 4 inward and slides on the outer surface thereof. Then, it overlaps with the bulged portion 4a, and the outer surface of one end comes into contact with the inner surface of the leg 2 and stops. In this state, one end of the pedal 5 is connected to the outer side of the leg 2.
Since it is suppressed by , it receives a large reaction force. During this time, one end of the elastic plate 4 is pressed by one end of the pedal 5 and deflects inward, and the brake pad 6 is pressed against the side surface of the wheel 3, thereby fixing the wheel 3. The brake pads 6 are made of elastic resin and have a large frictional force with the wheels 3, so that a large braking force can be obtained. At the same time as the pedal 5 overlaps the bulging portion 4a, the engaging portion 5a at the other end of the pedal 5 engages with the corresponding engaging portion 4b of the elastic plate 4 and is held in that state. Therefore, even if the wheel 3 is subjected to vibration and the brake pad 6 is repeatedly slightly compressed and restored, there is no fear that the pedal 5 will shift or move.
To release the brake, the pedal 5 may be depressed in the opposite direction and rotated in the opposite direction.

Stop at. During this time, the sliding slope 5e of the pedal 5 rides on the bulge 4a of the elastic plate 4, slides while pressing it inward, and stops with its upper outer edge in contact with the inner surface 2a of the leg 2. do. Therefore, the elastic plate 4 is the pressing piece 5
d and deflects inward, and the brake pad 6 is pressed against the side surface of the wheel 3, preventing its rotation. The pressing piece 5d cooperates with the inner surface 2a of the leg 2 to press and hold the brake piece 4c of the elastic plate 4 inward. Further, in this state, the engaging part 5a of the pedal 5 is fitted into the engaging part 4b of the elastic plate 4, and the brake is held so that it will not easily come off due to external force such as vibration. If you press down on the treadle 5b of the pedal 5, the second
The state returns to the state shown in Figure 3 and the brake is released.

出来るという効果を有する。(Effects of the invention) As described above, in the present invention, an elastic plate 4 is attached to the leg 2 that supports the wheel 3 pivotably along the side surface of the wheel 3, and a pedal is attached to the outside of the elastic plate 4 coaxially with the wheel 3. 5 is pivoted, and when the pedal 5 rotates, the elastic plate 4 is bent inward and brought into pressure contact with the side surface of the wheel 3. One end of the elastic plate 4 is attached to the inside of the leg 2. A brake pad 6 made of elastic resin is fixed to the inside of this bulge 4a, and the other end of the elastic plate 4 has a bulge 4a that bulges outward. The pedal 5 is provided with an engaging portion 4b that engages with the pedal 5, and when the pedal 5 is rotated in one direction, the one end overlaps the outside of the bulging portion 4a of the elastic plate 4 and is able to press the bulged portion 4a inward. , the outer side can come into contact with the inner side of the leg 2 when superposed with the bulge 4a, and one end of the pedal 5 is connected to the bulge 4 of the elastic plate 4.
Since a configuration is adopted in which a corresponding engaging part 5a is provided which is elastically engaged with the engaging part when superimposed, the friction between the brake pad 6 made of elastic resin and the wheel 3 is large.
It is possible to perform a reliable braking action, and when the side surface of one end of the pedal 5 comes into contact with the inner surface of the leg 2 during braking action, the two work together to press the brake pad 6 against the wheel with a large force, and also to reduce the reaction force. Furthermore, the braking state can be reliably maintained by the engagement of the engaging portions 4b and 5a.
