By using our crawl-type mechanism, we have been developed stairlift, powered wheelchair and slope-car which can move up and down along staircase or slope. Elderly or handicapped people can easily and effectively go to desired place by using these devices. Carrier plate using crawl-type mechanism is supported and traveled on two traction guides and is driven by reaction force caused on one roller attached on motor driven disc and drive guide set up between the traction guides. Each traction guides roller were composed of one pair rollers hold on each traction guide. This structure is useful for moving along helical staircase, but moving stability along the horizontal traction guide is poor relative to moving on the slope parts. In order to raise up the moving stability on the horizontal one, 3 roller-type is adoped instead of one pair roller type. Shape modification of circular arc part, needed for connecting the guide whose slope angle is different, of traction guide is presented here.
