Abstract: A work transfer device employed in a multi-process press machine is provided with a drive unit formed of a servo motor, a cam shaft vertically provided so as to be rotatably driven by the drive unit, a cam mechanism formed of three cams including an X-axis feed cam that moves a feed bar provided with a work holding fitting for holding a work toward an X-axis direction, a Y-axis feed cam that moves the feed bar in parallel toward a Y-axis direction in parallel, and a Z-axis feed cam that moves the feed bar in parallel toward a Z-axis direction, a group of swing levers formed of three types of swing levers which are swingably operated in engagement with the corresponding cams that constitute the cam mechanism, and a link mechanism connected to each end portion of the swing levers such that the feed bar is linearly driven toward the X-axis, Y-axis, and Z-axis directions.

Abstract: A playing vehicle is disclosed in which a human may ride on the vehicle body in a mode wherein he sits thereon while his legs are stretched and in which the body weight may be one-sided to either the left or right, thereby changing the travelling direction. The playing vehicle comprises bearings pivoted to the vehicle body by means of king pins, resilient members interposed between the vehicle body and the bearings, wheels supported on both bearings, and a prime mover placed on a mount. Both legs of a triangle whose base is a horizontal phantom line depicted longitudinally of the surface of the vehicle body is aligned with the inclining direction of the front and rear king pins.
