LOW-FREQUENCY TREATMENT DEVICE, MAIN BODY PORTION FOR LOW-FREQUENCY TREATMENT DEVICE, PAD FOR LOW-FREQUENCY TREATMENT DEVICE, COMBINATION OF PAD AND HOLDER FOR LOW-FREQUENCY TREATMENT DEVICE

摘要

A low-frequency treatment device includes: a pad configured to be attached to a body of a user; a holder configured to hold the pad; and a main body portion configured to be attached to the holder. The holder and the main body portion are engaged, with a clearance of a predetermined distance for arranging the pad being formed therebetween. Electrical conduction established between a pad-side electrode portion included on the pad and a main body portion-side electrode portion included on the main body portion by coming into contact with each other in the clearance of the predetermined distance. At least one electrode portion among the pad-side electrode portion and the main body portion-side electrode portion can perform movement in a direction of approaching and separating from the other electrode portion and is biased in the approaching direction.
