  • Patent number: 11918531
    Abstract: Provided is a thermotherapy device, which includes a first housing (10), a second housing (20) disposed under the first housing (10), a transfer plate (30), at both sides of which transfer rollers (31) are provided, and a pair of guide rails (40) that is provided to the second housing (20) and on which the respective transfer rollers (31) of the transfer plate (30) are placed. The pair of guide rails (40) are integrally molded when the second housing (20) is injection-molded. Thus, since the guide rails on which the transfer rollers of the transfer plate travel are integrally molded when the second housing is injection-molded, inefficiency caused by mounting separate rails as in the related art is removed, and thereby assemblability, productivity, and economic efficiency of the thermotherapy device can be improved.
