The invention discloses a far-infrared physiotherapy device for feet. The device comprises a base frame; an annular guiding block is fixed on the top of the base frame; and an annular groove is formedin the top of the annular guiding block. An upper plate body is arranged right above the annular guiding block; and an annular self-lubricating block is fixed on the bottom of the upper plate body, is plugged in the annular groove and is pressed against the bottom surface of the annular groove. Vertical plates are fixed at the left side and the right side of the upper plate body; lateral groovesare formed in the inner side walls of the two vertical plates; a main shell body is arranged in the lateral grooves; and the inner side walls of the main shell body are fixed in the inner side walls of the lateral grooves. A circular block is fixed on the top in the middle of the upper plate body. A lower groove is formed in the middle of the bottom of a guiding plate; a circular block is pluggedinto the lower groove; self-lubricating layers are fixed on the bottom and the side wall of the lower groove; and the top and the side wall of the circular block are in contact with the self-lubricating layers tightly. According to the invention, a foot can be placed on a pedal plate; and with rotation of the upper plate body, automatic rotation of the foot is realized and infrared irradiation isalso carried out. The irradiation is done uniformly and the effect is good.
