Abstract: A leg massager achieves easy changing of massaging positions and is also adaptable to user's legs of varying lengths by using a position-adjustable massaging system for performing massage on massage target areas of a user's legs. The leg massager includes a lower massaging system for massaging a massage target area of the user's leg including at least the user's foot; an upper massaging system for massaging an upper massage target area located above the massage target area which is massaged by the lower massaging system; a rockably supporting system that supports the upper massaging system for rocking motion about a horizontal-pointing axis in a front-rear direction; and a vertically moving system that permits up-and-down movement of the upper massaging system.

Abstract: A massaging apparatus minimizes the application of an excessive load to a massage target area of user's body from a massaging element firmly pressed into contact with the massage target area, provides satisfactory massage treatment, and distributes an excessive load imposed on the massaging element to protect the massaging apparatus itself from damage such as breakage. The massaging apparatus includes a massaging element for performing massage treatment on a massage target area of user's body, and an arm member provided at its head with the massaging element. The arm member has load-reducing mechanism for absorbing a load applied to the arm member from the massaging element. The load-reducing mechanism absorbs a load imposed on the massaging element by exploiting an urgence exerted in a front-rear direction.
