Abstract: A power supply device comprises a battery assembly formed by stacking secondary battery cells having safety valves for exhausting gas, end plates being arranged at both end faces of the battery assembly in the stacking direction, a gas duct guiding gas emitted from the safety valves in a prescribed gas exhaust passage, and fixing portions fixing both ends of the gas duct to the end plates in a position where the gas duct faces the safety valves. In a state in which the gas duct is fixed to the end plates in at least one of the fixing portion a fixing opening of a slit is formed extending in the direction parallel to the direction in which the secondary battery cells are stacked, and a fixing member is inserted into the slit fixing opening.

Abstract: The invention provides a massage machine wherein massage arms provided with kneading balls are held inclined forward to give a suitable massage. The massage machine comprises a kneading shaft (40) disposed on the massage unit (20) substantially horizontally, pivotal levers (33),(33) supported by the kneading shaft (40), massage arms (32),(32) supported by forward ends of the respective pivotal lever and kneading balls (31),(31) provided on the respective massage arms each at a position obliquely above the position where the massage arm is supported by the pivotal lever. An arm lock mechanism (80) is coupled to the massage unit for holding the kneading balls pushed out forward, and the arm lock mechanism tiltably supports arm lock rods (83),(83) each having one end connected to the massage arm at a position away from the position where the massage arm is supported by the pivotal lever.

Abstract: The invention provides a massage machine comprising a massage unit which itself can be pushed out relative to a backrest to thereby enable therapeutic fingers to be pushed out by a great amount. The massage machine comprises a backrest (12) provided on a chair for the person to be massaged to sit in, and a massage unit (20) reciprocatingly movable upward and downward longitudinally of the backrest (12) and having a pair of therapeutic fingers (30), (30) projecting from the backrest (12). The machine further comprises a pushing-out mechanism (60) for moving the massage unit (20) forward or rearward relative to the backrest (12).

Abstract: The invention provides a massage machine of the chair type having contact portions for applying a pressing force concentrically or dividedly so as to massage the user with the desired intensity. The machine comprises a massage unit having a first therapeutic finger for giving tapping massage to the upper part or the upper to frontal part of the shoulder of the user, and a second therapeutic finger for giving tapping massage to the back or the back to the posterior part of the shoulder. The fingers each have a portion to be brought into contact with the user at the forward end of an arm. The arms are pivotally movable independently of each other by respective finger drive means.

Abstract: A massage machine is provided which is adapted for effective massage by initiating a pair of therapeutic fingers into a lateral movement toward or away from each other approximately simultaneously with the start of an upward or downward movement of the fingers.
