ロックレバー５５から構成されている。2. Description of the Related Art FIGS. 3A, 3B and 3C are a plan view, a side view and a front view of a conventional caster. The caster includes a pair of wheels 51, a support member 53 for rotatably supporting a shaft 52 of the wheels 51, and a mounting plate 54 for rotatably attaching the support member 53 to the bottom surface of the article.
And a lock lever 55 for fixing the shaft 52 of the wheel 51 to the support member 53.

車輪５１や支持部材５３が邪魔になることはない。When the caster is mounted on the bottom surface of an article, a screw 5 is inserted into a mounting hole 56 formed in a mounting plate 54.
7 is screwed into the bottom of the article. Since the center of rotation of the wheel 51 and the center of rotation of the support member 53 rotatably mounted on the mounting plate 54 are offset, when the caster is mounted on the bottom surface of the article with the screw 57,
The wheels 51 and the support members 53 do not interfere.

る。However, for example,
In the case of a caster, such as a step caster, which has a projection for climbing over the rotation center of the support member on the opposite side to the rotation center of the wheel, this projection is an obstacle, and Casters cannot be mounted on mounting plates of the same size. For this reason, it is necessary to form the mounting hole at a position where another member does not interfere when mounting the screw by increasing the diameter of the mounting plate.

上昇を招くという問題があった。[0005] However, when the diameter of the mounting plate is increased as described above, the caster becomes large and a mounting plate dedicated to the step caster must be prepared, so that there is a problem that the manufacturing cost of the caster increases. In addition, if the position of the mounting hole changes, the step caster cannot be directly attached instead of the normal caster. However, there is a problem that the manufacturing cost of the device is increased.
