To follow up a preceding vehicle smoothly without making an impact on loaded articles or occupants.SOLUTION: A self-propelled followup vehicle includes a sensing unit 5 capable of being brought into contact with/separated from a preceding vehicle, and a transmission unit 4 for shifting turning force. The sensing unit includes an extendable contact plate 51, and a gas spring 53 for energizing the contact plate in an advancing direction. The transmission unit 4 consists of a hydrostatic non-stage transmission 41 and a gear box, and includes a link mechanism interlocking with the sensing unit. The link mechanism consists of an intermediate lever 46, and a first lever 47 and a second lever 48 pivoted to both end parts of the intermediate lever. The intermediate lever is provided with a first pin 46a loosely fitted to the first lever at one end, and is provided with a second pin 46b with which the second lever comes in contact at the other end in a projecting manner. The first lever is connected to an operation shaft of the transmission unit at one end, and is loosely fitted to the intermediate lever at the other end. The second lever is pivoted coaxially with a rotation fulcrum shaft 46c of the intermediate lever at the base end part, and connected to the sensing unit by a linkage member 55.SELECTED DRAWING: Figure 2

    【課題】積載した物品や乗員に衝撃を与えずに、滑らかに先行車に追随することができること。【解決手段】先行車に接触/分離可能な感知部5と回転力を変速する変速部4とからなる。感知部は伸縮自在の当接板51と当接板を前進方向に付勢するガススプリング53とからなる。変速部4は静油圧式無段変速機41及びギヤボックスからなり、感知部に連動するリンク機構を備える。リンク機構は中間レバー46と中間レバーの両端部に枢着される第1レバー47及び第2レバー48からなる。中間レバーは一端部に第1レバーに遊嵌される第1ピン46aが設けられるとともに、他端部に第2レバーが当接される第2ピン46bが突設される。第1レバーは一端部が変速部の操作軸に連結され、他端部にて上記中間レバーに遊嵌される。第2レバーは基端部が上記中間レバーの回動支点軸46cと同軸に枢着されるとともに連係部材55により感知部に連結される。【選択図】図2
