LEVER DEVICE AND WORK MACHINE PROVIDED WITH THE SAME
To provide a lever device which is inexpensive and highly operable.SOLUTION: A cam groove has an upper groove part, an intermediate groove part, and a lower groove part. A lever can be oscillated between a pressed-down position where a guide pin is disposed on the upper groove part and a pulled-up position where the guide pin is disposed on the lower groove part. The cam groove is provided at a position before a second horizontal shaft which is a rotary shaft of a cam body. A first biasing member is connected at one end to a first connection part which is provided at a base and at the other end to a second connection part which is provided at the cam body, and disposed behind the second horizontal shaft when the lever is at the pressed-down position and before the second horizontal shaft when the lever is at the pulled-up position.SELECTED DRAWING: Figure 8
【課題】安価で操作性の良いレバー装置を提供する。【解決手段】カム溝は上溝部と中間溝部と下溝部とを有し、レバーはガイドピンが上溝部に配置される押し下げ位置とガイドピンが下溝部に配置される引き上げ位置とに揺動可能であり、カム溝はカム体の回動軸である第２横軸よりも前方の位置に設けられており、第１付勢部材は、一端側がベース台に設けられた第１接続部に接続され、他端側がカム体に設けられた第２接続部に接続されており、レバーが押し下げ位置にあるときには第２横軸よりも後方に配置され、レバーが引き上げ位置にあるときには第２横軸よりも前方に配置される。【選択図】図８
