A guiding and anti-backlash structure is providing for connecting a wheelchair and a control stem of the wheelchair. The guiding and anti-backlash structure includes a set of mounting frame disposed on a front portion of the wheelchair and a concave portion defined in the set of mounting frame. A rod is mounted onto the control stem. The rod is selectively and detachably engaged to the concave portion such that the control stem is pivotal relative to the mounting frame. The rod has two opposite ends each having an anti-backlash element mounted thereon for preventing the control stem from being swung relative to the mounting frame and guiding the rod to be quickly mounted into the concave portion.本發明係提供一種供結合輪椅與其操控桿之導引消隙結構，操控桿係利用該導引消隙結構組配於輪椅上，該導引消隙結構主要包括：一組裝定位架，係設於該輪椅前側；一限位凹部，設於該組裝定位架前端；一卡接桿，設於該操控桿上，該卡接桿選擇性地樞組於該限位凹部內，並構成該操控桿相對該組裝定位架呈可旋轉擺動態樣；以及一對消隙定位構件，分別設於該卡接桿之兩端，用以避免該操控桿相對該組裝定位架左右晃動，並且導引該卡接桿迅速地對應組設至該限位凹部內之效用。
