Abstract: The present invention provides an article pushing device for pushing an array of hanging articles along a hook bar by the action of self-restoring force of a compression spring body which can be elastically compressed with no space loss and be easily fitted on a hook bar without previously taking off the articles. The device comprises a zigzag leaf-spring body having a series of sharp alternate turns forming peaks and bottoms, which spring body can be contracted with substantially no space between neighboring parallel leaf-portions and has a series of notches (sliding holes with an open slit) made in peaks thereof for externally fitting onto the hook bar. The zigzag leaf-spring body is provided with a pushing portion at its front end and a holding member at its rear end.

Abstract: A stepless speed change gear has an axially movable speed changing ring that is frictionally engaged with a plurality of conical rollers. The stepless gear has improved durability and reduced weight due to a flat annular power transmitting surface and an annular power transmitting surface of arcuate cross-sectional contour on the bottom portion of each conical roller. A force caused by a contact pressure generating device is applied to the conical rollers at the annular power transmitting surface of arcuate cross-sectional contour, so as to advance the conical rollers into a space between the speed changing ring and another frictionally engaging member as a wedge so that required contact pressures are applied on the frictionally engaging points.

Abstract: A vehicle with a new propulsion mechanism is disclosed. This vehicle is driven by a rider making reciprocal lateral swings by means of one or more rods, each of which carries a ground-contacting propelling member (a wheel, a ski or a skate) through a pivotal joint and a carrier, such as a fork, for the propelling member. In most cases, the vehicle is constructed as a cycle. This cycle can be constructed as one which is used by a rider who cannot move his foot for the purpose of propelling the cycle.The locus of the ground-contact-point of the propelling member is a meandering one.
