As a kind of preferred version of such scheme, said universal wheel is plate universal wheel.Adopt plate universal wheel, when universal wheel and spring were affixed, contact-making surface was big, and it is firm to connect.
As a kind of preferred version of such scheme, said chair back inner face is vertically arranged with two raised lines.When people leaned against on the raised line, raised line can play the effect of massage.
As a kind of preferred version of such scheme, said wheel is processed by rubber or metal material.Rubber or metal wheel are more wear-resisting, long service life, and little with the frictional force on ground.
The beneficial effect of the utility model is:
1. when taking a seat among the roller indentation chair leg, can guarantee that chair is stable and do not slide.
2. stand up or nobody when taking a seat roller stretch out outside the chair leg, avoided the friction on chair shank and ground, can easily move chair again.
