LOW-FREQUENCY TREATMENT DEVICE, PAD FOR LOW-FREQUENCY TREATMENT DEVICE, MAIN BODY PORTION FOR LOW-FREQUENCY TREATMENT DEVICE, HOLDER FOR LOW-FREQUENCY TREATMENT DEVICE, AND COMBINATION OF PAD AND HOLDER FOR LOW-FREQUENCY TREATMENT DEVICE
The present invention includes a guiding engagement portion configured such that a holder and a main body portion for supplying a low-frequency pulse current to a pad engage in a state in which the main body portion is attached to the holder, and the holder and the main body portion are disengaged in a state in which the main body portion is removed. The guiding engagement portion is formed so as to allow the holder and the main body portion to engage by moving in a direction of approaching each other during the attachment, and during the removal, disengage the holder and the main body portion by restricting movement in a direction opposite to the movement direction during the attachment, and allowing the main body portion to move with respect to the holder in a direction intersecting the direction of approaching each other.
