PROBLEM TO BE SOLVED: To reduce a size of a driving wheel unit of an automatic conveyance carrier.SOLUTION: A driving wheel unit 3 is fitted to an automatic conveyance carrier 1 having a carrier body 11 and plural casters 12 which support the carrier body from below, and drives the automatic conveyance carrier. The driving wheel unit comprises: an arm support part 31 which can be fitted to the carrier body; an arm 32 which is so supported as to be rotatable around a fulcrum 311 of the arm support part; a drive wheel 33 which is connected to the arm; a drive mechanism 34 which is connected to the drive wheel and rotationally drives the drive wheel; and an elastic member 35 which is elastically deformed between the arm and the arm support part, and gives a downward force to the drive wheel. A fulcrum of the arm support part fitted to the carrier body is positioned between a top edge and a bottom edge of the drive wheel in a vertical direction.SELECTED DRAWING: Figure 2
【課題】自動搬送台車の駆動輪ユニットを小型化する。【解決手段】駆動輪ユニット3は、台車本体11と、台車本体を下方から支持する複数のキャスタ12と、を有する自動搬送台車1に取り付けられて、自動搬送台車を駆動する。当該駆動輪ユニットは、台車本体に取り付け可能なアーム支持部31と、アーム支持部の支点311を中心として回転可能に支持されるアーム32と、アームに接続される駆動輪33と、駆動輪に接続されて駆動輪を回転駆動する駆動機構34と、アームと前記アーム支持部との間にて弾性変形し、駆動輪に対して下方に向かう力を付与する弾性部材35と、を備え、台車本体に取り付けられたアーム支持部の支点が、上下方向において駆動輪の上端と下端との間に位置する。【選択図】図2
