  However, in the conventional casters and carts of this type, in which the wheel portion swings in response to the unevenness and inclination of the running surface in this way, the caster main body and cart of the wheel portion are intended. The swinging action mechanism for the main body is supported simply via a small-diameter / small-diameter support shaft so as to enable swinging. For this reason, for example, it is impossible to support the weight of various devices even if it is incorporated as a caster for moving and supporting large devices in a factory that is heavy in weight, or as a swing mechanism for a carriage. For this reason, it may be damaged during use of traveling.

  Therefore, the present invention was created in view of the existing circumstances as described above, and its purpose is to convey a roller base body and a transported object that roll on the transport surface when transporting and moving heavy equipment. To provide a transport roller that can move and transport in a stable manner by making it possible to cope with rocking in response to irregularities, inclinations, etc. on the transport moving surface by a swinging action with the top plate portion that supports and supports is there.

In order to solve the above-described problems, in the present invention, the roller base body 1 on which the roller 5 is rotatably supported, and the roller base body 1 in the front-rear direction of the roller base body 1 by the swing shaft 14. The transported object mounting unit 10 includes a bridge 11 that is swingably supported by the roller base body 1 and a bridge 11 at the center of the bridge 11. The bridge 11 is formed on the upper plate 12 covering the opened upper opening portion of the roller base body 1 together with the left and right side walls 3 of the roller base body 1. A support leg piece 13 through which the moving shaft 14 is inserted is provided, and the top plate 15 is rotatably fitted to a rotary shaft portion 16 provided at a substantially central portion of the upper plate 12.
A belt-shaped closing plate 8 is mounted on the front and rear end portions of the upper portion of the roller base body 1 so as to close a part of the opening portion, and the bottom surfaces of the front and rear edges of the closing plate 8 on the opening portion side.

In the transport roller according to the present invention configured as described above, when a predetermined transport object P is mounted on the transport object mounting portion 10 and the roller base body 1 is traveled, the travel surface is uneven, an inclined surface, or the like. If there is, the roller base body 1 swings with respect to the transported object mounting portion 10 via the swinging shaft 14 that supports the weight of the transported object P, thereby avoiding these and moving smoothly.
The conveyed product mounting part 10 is connected to the open part of the upper part of the roller base body 1 in a swingable manner, and the conveyed product mounting part 10 and the roller base are processed by chamfering the bottom surfaces of the closing plate 8 and the upper plate 12 of the open part. The roller 5 is not brought into contact with the conveyed product mounting portion 10 when swinging with the main body 1.
The left and right side edge portions of the upper plate 12 abut against the upper edges of the left and right side walls 3 of the roller base body 1 when the transported object mounting portion 10 and the roller base body 1 swing, so that the swing range is within a certain range. Therefore, an excessive load is not applied to each of the transported article mounting unit 10 and the roller base body 1.

  Since the present invention is configured as described above, when a predetermined transport object P that is bulky such as various devices is mounted on the transport object mounting unit 10 and is moved and moved by the roller 5 of the roller base body 1. Even if the moving running surface has irregularities, inclinations, etc., the roller base body 1 can be swung to avoid it and can be transported smoothly.

  In other words, in this device, the roller base body 1 and the transported object mounting unit 10 are connected to each other by a swing shaft 14 so as to be swingable in the front-rear direction. A top plate 15 is pivotally supported on a bridge 11 that is movably supported, and the bridge 11 is formed on an upper plate 12 that covers an open upper opening portion of the roller base body 1 and left and right side walls of the roller base body 1. 3 is provided with a support leg piece 13 through which the rocking shaft 14 is inserted, and the top plate 15 is rotatably fitted to a rotary shaft portion 16 provided at a substantially central portion of the upper plate 12. . Thereby, the roller base body 1 swings corresponding to the unevenness and inclination of the moving surface during the transport movement, the swing connection by the swing shaft 14 capable of withstanding the weight of the transported object P, and the direction change during the transport movement is easy. Such excellent effects can be obtained.

  Further, chamfering processing is performed on the bottom surface of the front and rear edges of the open block side of the mounted closing plate 8 that closes a part of the open part of the upper part of the roller base body 1 and the bottom surface of the front and rear edges of the upper plate 12 of the bridge 11. Therefore, even when the roller base body 1 swings with respect to the transport object mounting portion 10 on which the transport object P is mounted, the roller 5 of the roller base body 1 is brought into contact with the transport object mounting portion 10. The running rotation by the roller 5 is not hindered.

  The swing between the transported article mounting unit 10 and the roller base body 1 is within a certain range because the left and right side edge portions of the upper plate 12 of the bridge 11 abut against the upper edges of the left and right side walls 3 of the roller base body 1. Since it is regulated, it does not swing more than necessary, and can travel and travel safely and stably without applying a large load.
