Abstract: An omnidirectional wheel whose outer circumference surface is formed by pluralities of rollers, and includes a rotating part that rotates around a rotation axis. A plurality of supports are arranged in a circumferential direction of the rotating part and each mounted on the rotating part. The rollers include a plurality of first rollers and a plurality of second rollers. Each support has a first arm supporting one end side of a corresponding first roller of the plurality of first rollers, and a second arm supporting the other end side of the corresponding first roller. A corresponding second roller of the plurality of second rollers is supported by the first arm of one of two supports that are adjacent to each other in the circumferential direction and the second arm of the other one of the two supports.

Abstract: The omnidirectional wheel includes a first support portion which rotates around a rotation axis line, a second support portion which rotates together with the first plate-like member, a number of support shafts respectively supporting a number of rollers, and a number of support plates fixed to the first and the second support portions and which support one or more of the support shafts between the first and second support portions.

Abstract: Provided is an omni-directional wheel including a substantially cylindrical hub provided so as to be rotatable around an axle; a plurality of rollers which have axes extending in a direction intersecting a radial direction of the hub and of each of which an outline has a curvature equal to a curvature of a circle centered at the axle; a support part which allows the rollers to be mounted so as to be rotatable around the respective axes, which supports the rollers such that the outlines are arranged on a single circumference; and rubber tubes which are held between and in contact between the outer circumferential surface of a cylindrical part of the hub and the inner circumferential surface of the support part in the radial direction.

Abstract: The omni-directional wheel includes first support parts and second support parts which support large-diameter rollers and small-diameter rollers. Each of the first support parts is disposed at a position where the first support part is held between a pair of the large-diameter rollers, while each of the second support parts is disposed at a position where the second support part is held between a pair of the small-diameter rollers. The large-diameter rollers and the small-diameter rollers are disposed such that their outlines are arranged on a single circumference, with a part of the small diameter-side end face of the small-diameter rollers partially inserted in the recessed portions of the large-diameter rollers.

Abstract: Automatic collection and set up equipment for chairs, characterized by the fact that it performs automatically all the jobs required in collecting and setting up chairs; markedly reduces the man-hours required to prepare a conference room; and it has an arrangement of many hooks which are able to move up or down at short intervals, in line, on a truck picking up or letting down crossmembers of the chairs and stacking chairs one by one.

Abstract: A method and apparatus for cleaning the faces of plastic forming metal molds in which brush members opposite to the mold faces are vibrated by a suitable vibration-applying member. The tips of the brush members beat and break flashes of residual plastic stuck to the metal mold faces, thereby to remove the flashes. The thus removed flashes are sucked and taken out from the metal mold faces by sucking means, thus cleaning the metal mold faces.
