In some cases, it is not possible to recycle them, so that they may be treated roughly and damaged recyclable equipment, making it impossible to recycle them and disposing them as waste.
[0003]
In order to cope with this, it is conceivable to install an alternative caster in place of a broken or damaged caster on the bottom of the device. Needless to say, when attaching an alternative caster to the bottom surface of a device where the caster is damaged or damaged, it is desirable to attach the original caster at the four corners of the bottom of the device (see, for example, Japanese Utility Model Publication No. 6-62574). ) Generally, it is not easy to remove a broken or damaged caster. For example, in what is disclosed in Japanese Utility Model Laid-Open No. 5-74905 and Japanese Patent Application Laid-Open No. 11-59432, the caster attachment member is devised to facilitate attachment to the apparatus main body side, but it is premised on recycling. Casters cannot be easily replaced. Therefore, it is necessary to attach the alternative caster while avoiding the mounting position of the existing caster. Therefore, it is necessary to make the mounting surface of the alternative caster to the equipment bottom flat so that it can be attached to any place on the equipment bottom.
[0004]
Also, depending on the size and weight of the equipment, it is necessary to disperse the load resistance applied to the casters. Therefore, it is necessary to adopt a system that can mount a plurality of casters.
