A robot apparatus that is able to perform jumping. In a leg structure of the robot apparatus, connecting bars and pivots to constitute a four-point link mechanism. A rod is inserted into an opening formed in the distal end of a leg part . A coil spring as an elastic member is provided between one end of the rod and the distal end of the leg part . A bar member is connected and secured to a preset point of a connecting member as a knee joint. The coil spring is extended/contracted by the stretching/contraction of the connecting member . By the operation of the four-point link mechanism, the trajectory of the distal end of the leg part is linear. The coil spring is mounted at a position such that the distance between a driving shaft and the distal end of the bar member has a substantially linear relationship with respect to the force virtually operating between a driving shaft and the distal end of the bar member
