[Effects of the present invention] As is clear from the above description, the following effects can be obtained in the present invention.

(1) A base plate body formed of a synthetic resin material into a square or rectangular plate shape, a portion near the center both ends, a portion near one end and a portion near the center both sides of the base plate body. Handle or through hole formed at a portion near one side or a portion close to one side, and a side member into which the other side of another base plate body formed on the upper surface of one side of the base plate body enters. A mating concave portion, an end engaging concave portion formed on the upper surface of one end portion of the base plate main body, into which the other end portion of the other main plate main body enters, and an outside portion of a through hole in the other side portion of the base plate main body A side engaging piece that protrudes downward and is inserted into a through-hole of another base plate body, and protrudes downward into an outer portion of a through-hole at the other end of the base plate body, and is formed through the other base plate body. An end engaging piece inserted into the hole,
4 fixed to the bottom near the four corners of the base plate body, respectively.
Since it is composed of a plurality of casters, it can be used alone to transfer the load by loading the load on the base plate main body, or can be used by connecting a plurality of them in the front-back, left-right direction.
Therefore, it is possible to make the size suitable for the size of the luggage and use it in an optimal state.

(2) According to the above (1), the other side of the other carrier enters into the side engaging recess of one carrier, and the side of the other carrier enters the through hole of one carrier. Since the engagement pieces are engaged, the two carriers can be reliably connected in a parallel state. Therefore, two carriers can be used in an integrated state.

(3) According to the above (1), the other end of the other carrier enters the end engaging recess of one carrier, and the end of the other carrier enters the through hole of one carrier. Since the engagement pieces are engaged, the two carriers can be reliably connected in series. Therefore, the two carriers can be used in an integrated state in series.

(4) By the above (1), the through holes for forming the handles are formed in the portions near the center both ends and near the both sides of the base plate body, respectively.
When carrying the carrier, the hand can be inserted into the through hole for forming the handle and lifted. Therefore, it can be easily carried.

(5) According to the above (1), since there is no protrusion projecting outward or a recess opening on the outer periphery, even if it hits with another bogie or the like during use, it is surely prevented from getting entangled. Since it does not protrude or dent from the outer peripheral portion, it has a simple and clean structure, and can be manufactured at low cost.

(6) According to the second aspect, the same effects as in the above (1) to (5) can be obtained, the base plate main body has sufficient strength, and the casters can be easily attached.

(7) Claims 3 and 4 can also be used by connecting them in the front-rear direction or the left-right direction.
