Abstract:
A slide rail is configured so as to be simple and at the same time so as to allow an inner rail to move smoothly. A second rail (2) is provided with a pair of opposing inner surfaces, and longitudinally extending rolling sections (6, 7) are formed respectively on the pair of inner surfaces. A first rail (1) is provided with: a first wheel (31) provided so as to be rotatable about a first axis; a second wheel (32) provided so as to be rotatable about a second axis which is separated from the first axis in the direction of movement of the first rail (1) so that the second wheel (32) does not make contact with the first wheel (31); and a rolling body (33) in contact with the first wheel (31) and with the second wheel (32) in such a manner that the rolling body (33) can rotate in association with the rotation of the first wheel (31) and of the second wheel (32). The first wheel (31) and the second wheel (32) perform rolling motion on the rolling section (7) of one of the inner surfaces of the second rail (2). The rolling body (33) performs a rolling motion on the rolling section (6) of the other inner surface of the second rail (2).
Abstract:
PROBLEM TO BE SOLVED: To provide a door which has the characteristics of preventing a person from feeling the door heavy when opening the door, which is slowly revolved and tightly sealed, which makes an impact noise small in closing, and which prevents a finger pinching accident by temporarily stopping when a strong and rapid force acts on the door; and to make the door provided with the function of being fully opened when slightly opened and of being fully closed when slightly closed. SOLUTION: A structure decelerating without use of the viscosity resistance or direction resistance of oil is provided; a closing speed is controlled by changing the direction of a force; the door is revolved in the state of setting a spring force minimum; the device increases the spring force to the utmost limit by continuing to run even when the door is stopped immediately before being closed; and the impact noise is reduced by bringing about a sealed state via the first door.

Abstract:
PROBLEM TO BE SOLVED: To provide a sash roller capable of reducing a contact sound with a rail and of surely preventing the a crack in a portion coming into contact with the rail. SOLUTION: A resin rail contact member 20 is molded in an outer peripheral groove 10a of a metal body 10, so as to come into contact with the rail and reduce the contact sound. An axial locking portion 11b and an axial locking retainer portion 20d, which are locked to each other so as to prevent the axial displacement of the rail contact member 20, are formed on the outer peripheral surface 11a of the bottom wall portion 11 of the main body 10 and the inner peripheral surface 20b of the rail contact member 20, respectively. A circumferential locking portion 12b and a circumferential locking retainer portion 20e, which are locked to each other so as to prevent the circumferential displacement of the rail contact member 20, are formed on the inside surface 12a of the flange portion 12 of the main body 10 and the outside surface 20a of the rail contact member 20, respectively. Thus, the formation of the crack is prevented by suppressing deformation caused by a load of the rail contact member 20. COPYRIGHT: (C)2009,JPO&INPIT
