摘要： PROBLEM TO BE SOLVED: To provide an armrest device for smoothly rotating an armrest body with small force in the state between the housed state and the developed state.
SOLUTION: The armrest device includes: a fixed shaft 2; a rotary plate 3 which is rotatable integrally with the armrest body 4; a locking spring 5 with one end as a fixed-side hook 5a and the other end as a free-side hook 5b; a cam member 7 with a re-locking cam portion 7c which locks the locking spring 5 having a contracted diameter; and a stopper member 3b for stopping the rotation of a releasing block 8 at a fixed position. The abutting force acts on the releasing block 8 as the free-side hook 5b abuts to a spring receiving portion 8a, and the direction of the abutting force is diverged from the center of rotation of the releasing block 8 so that the releasing block 8 receives the rotation moment for the releasing block 8 to be pressed on the stopper member 3b by the abutting force.

摘要： PROBLEM TO BE SOLVED: To allow operation with one hand in movement in either lifting or lowering direction and to secure stable behavior without being influenced even by the attachment of slippery liquid such as soapsuds.
SOLUTION: This height adjusting device is provided with a base 2 allowing a shaft-like object member 6 to be inserted through in a reciprocating manner, and formed with a tapered face 7 intersecting an axial direction, at a part facing the object member 6; a locking member 3 having a shaft part 8 sliding along the tapered face 7, and a rotatable piece part 9 contacting the object member 6 in the passing state of the shaft part 8, and arranged to be axially movable between the tapered face 7 and the object member 6; and an elastic member 4 energizing the shaft part 8 to come in pressure contact with the tapered face 7. The movement of the object member 6 is locked by frictional force between the piece part 9 and the object member 6 by the energizing force of the elastic member 4. The movement of the object member 6 is allowed by the rotation of the piece part 9 due to the increase of frictional force with the object member 6 following the movement of the object member 6 in the energizing direction, while lock is released by the decrease of frictional force between the piece part 9 and the object member 6 by the movement of the locking member 3 in the same direction as the object member 6 by the movement of the object member 6 in an opposite direction to the energizing direction.
