    摘要: A hinge ball for a variable capacity wobble plate compressor includes a central through hole 27 for permitting a shaft 5 to loosely extend therethrough, and an outer peripheral wall 9b in a convex form for being slidably fit with an inner peripheral wall 43a in a concave form of a boss 43 of a drive hub 41 rotatively fitted on the shaft 5. The shaft 5 is higher in hardness than the hardness of the boss 43 of the drive hub 41, and the outer peripheral surface 9b in sliding contact with the inner peripheral surface 43a of the boss 43 of said drive hub 41 is lower in hardness than the hardness of the shaft 5 and the boss 43 of the drive hub 41 or equal in hardness thereto. The hardness of the inner peripheral wall 9a defining the central through hole 27 is made higher than the hardness of the boss 43 of the drive hub 41.

    摘要: A zoom lens barrel is provided having a plurality of lens groups which are moved with respect to one another along a predetermined path. The zoom lens barrel comprises a driving barrel which rotates about an optical axis of the plurality of lens groups and at least three telescoping barrels which are moved in the direction of the optical axis by rotation of the driving barrel. Each telescoping barrel which is mounted on an inner periphery of another telescoping barrel of the telescoping barrels, travels a greater distance along the optical axis direction than the another telescoping barrel. A lens group driving mechanism is provided for moving the plurality of lens groups in the optical axis direction by movement of the at least three telescoping barrels in the optical axis direction.

    摘要: A camera having a zoom lens barrel that includes an aperture size changing mechanism including a pair of light intercepting members which are inserted into a retracted from a rectangular-shaped photographing aperture of the camera for changing the photographing aperture size. The camera further includes a non-rotational cylinder which moves in the direction of the optical axis of the zoom lens without rotating. A rotational cylinder is also included and is driven to rotate with respect to the non-rotational cylinder about the optical axis. A gear supporting member is supported on the non-rotational cylinder. The gear supporting member includes a raised portion projecting toward the photographing aperture. The camera further includes a gear train which is supported on the gear supporting member for transmitting a drive force to the rotational cylinder. At least a part of the gear train is supported by the raised portion, which is formed such that the orthographic projection thereof may not overlap the pair of light intercepting members in the optical axis direction.

    摘要: A zoom lens barrel is disclosed with includes a stationary barrel. A rotatable cam ring is supported by the stationary barrel and is adapted to move along an optical axis direction in association with rotation of the rotatable cam ring. A lens guide ring is adapted to move together with the cam ring along the optical axis direction, and the cam ring is adapted to rotate relative to the lens guide ring, in association with axial movement of the cam ring. Cam grooves are provided for guiding the movement of at least two movable front and rear lens groups, with at least one groove being formed on the cam ring. Lens guide grooves are formed on the lens guide ring and are adapted to correspond to the cam grooves of the cam ring. At least one guide pin is provided which is adapted to extend through an associated cam groove and an associated lens guide groove. The cam grooves and lens guide grooves are shaped such that the movable lens groups can be moved along a predetermined track by the movement which results from axial movement and relative rotation of the cam ring and the lens guide ring.
