摘要:
A door opening and closing mechanism for opening and closing the door from the inside of a fuselage. A door pivotally supported at an opening portion of the fuselage includes first and second position restricting links each having one end pivotally supported on the fuselage with a door driving link having one end pivotally supported on the door. The other end of the second position restricting link is pivotally supported on a middle portion of the door driving link. The door opening/closing operation lever is provided at one end with a grip with the other end pivotally supported on the other end of the door driving link. The middle portion of the door opening/closing operation lever is pivotally supported on the other end of the first position restricting link. By pulling the grip toward the inside of the fuselage and thereafter pushing downward, the door can be closed.
摘要:
A frictional drive device comprises a pair of drive disks (48) each rotatably supported by a frame (2, 42) around a central axial line (A) in a mutually opposing relationship, and a pair of actuators (64) supported by the frame for individually rotatively actuating the drive disks and coaxially disposed with respect to the corresponding drive disks, a plurality of drive rollers (56) arranged along an outer periphery of each drive disk and each having a rotational center line so as to be rotatable along a plane which is neither parallel nor perpendicular to the central axial line, and an annular main wheel (85) disposed approximately coaxially with respect to the central axial line and engaged by the drive rollers of the drive disks, the main wheel comprising an annular member (86) and a plurality of driven rollers (92) supported along the annular member so as to be rotatable around a tangential line of the annular member. A speed reduction unit (72, 100) may be interposed between each actuator and the corresponding drive disk all in a coaxial relationship.
