The motorcycle foot support assembly has a foot support member, a rotation arm, a monolithic motorcycle-mounting bracket, and a releaseable bracket-to-arm locking mechanism. The rotation arm is attached between the inner surface of the foot support and the motorcycle-mounting bracket. The monolithic motorcycle-mounting bracket has a motorcycle-attachment portion and an arm-attachment portion, the latter portion for engagement with the rotation arm. The releaseable bracket-to-arm locking mechanism has an engagement pin that selectively engages with one of a plurality of predetermined stop holes whereby the releaseable bracket-to-arm locking mechanism may be selectively engaged to stop the relative rotation between the arm-attachment portion and the rotation-arm first end.

A support structure includes a base, a pair of stands, a top hinge, and a pair of holding arms. The stands are rotatably connected to one end of the base to support the base. The top hinge is rotatably connected to the other end of the base opposite to the stands. The rotation plane of the top hinge is perpendicular to the rotation plane of the stands. The holding arms are rotatably connected to the top hinge for holding an object at any desired angle.

A combination castor includes a control unit, a linking unit, and at least two castor units. The control unit includes at least one mounting seat, at least one bushing mounted in the at least one mounting seat, and a pedal pivotally located at a side of the at least one mounting seat. The linking unit includes a propeller shaft extended through the at least one bushing and locked onto the pedal, at least one rotation plate secured on the propeller shaft, and at least two links each pivotally connected with the at least one rotation plate and the respective castor unit. Thus, when the pedal is stepped, the propeller shaft is driven to rotate the at least one rotation plate which drives the links to operate the castor units so as to brake or position the castor units simultaneously.

An assist grip includes: a grip member to be gripped by a passenger, the grip member configured to be capable of being pulled out from a retraction position to a grip position; a base member which is fixed to the vehicle and which includes a rotation shaft; a rotation arm pivotally supported so as to be rotatable about the rotation shaft from the retraction position to a pull-out position; retraction biasing element configured to always bias the rotation arm in a retraction direction; and a holding member configured to hold the rotation arm in the pull-out position against a biasing force of the retraction biasing element when the rotation arm is caused to rotate to the pull-out position. In the assist grip, the grip member is rotatably jointed to the rotation arm, and the grip member is provided with a release dog formed therein, the release dog configured to release the rotation arm from being held by the holding member as the grip member is rotated.

A withdrawing mechanism includes a striker disposed on one of a swingable member and a main body, a catcher disposed on the other of the swingable member and the main body, and a damper for applying a damping force to a turning operation of the catcher toward a turned position. The catcher includes a casing, a rotational plate having a hooking groove for catching the striker therein, and a spring attached between an attaching portion of the rotational plate and a fixing portion of the casing to pull and rotate the rotational plate.When the rotation plate catches the striker, the rotational plate rotates in a direction to pull the spring, and when the attaching portion passes a position on a linear line extending the attaching portion, rotational center of the rotational plate and fixing portion, the rotational plate is pulled to move the rotational plate to the turned position.

An assist grip includes: a grip member to be gripped by a passenger, the grip member configured to be capable of being pulled out from a retraction position to a grip position; a base member which is fixed to the vehicle and which includes a rotation shaft; a rotation arm pivotally supported so as to be rotatable about the rotation shaft from the retraction position to a pull-out position; retraction biasing means configured to always bias the rotation arm in a retraction direction; and a holding member configured to hold the rotation arm in the pull-out position against a biasing force of the retraction biasing means when the rotation arm is caused to rotate to the pull-out position. In the assist grip, the grip member is rotatably jointed to the rotation arm, and the grip member is provided with a release dog formed therein, the release dog configured to release the rotation arm from being held by the holding member as the grip member is rotated.

A machine tool has a Z table sliding in the Z direction in a horizontal plane, a support body provided on the Z table and sliding in the vertical direction, a rotation arm supported at the support body and endlessly rotatable in a vertical plane facing work, an arm motor for rotating the rotation arm, a processing spindle rotatably supported and placed at a position of a distance R from the center C of rotation of the rotation arm, and a spindle motor for rotating the processing spindle.

A light quantity adjustment apparatus comprises a support plate comprising a first through hole through which light passes; a rotation plate comprising a second through hole corresponding to the first through hole and rotatably disposed with respect to the support plate; a plurality of 2D iris plates rotatably connected to the support plate so as to move between an open location in which the first through hole is completely opened and a closed location in which the first through hole is completely closed, the plurality of 2D iris plates engaged with the rotation plate and adjusting an open area of the first through hole according to a rotation of the rotation plate; two 3D iris plates each having one end rotatably connected to the support plate and another end engaged with the rotation plate, the two 3D iris plates moving between a retreat location away from the first through hole according to the rotation of the rotation plate and a photographing location where a first photographing hole and a second photographing hole are formed by covering a part of the first through hole; a shading plate that moves between an operating location where the first photographing hole or the second photographing hole is closed and a stop location away from the first through hole; and a shading plate driving unit that drives the shading plate.

A position adjusting mechanism, a rotation-axle bearing mechanism, and a rotation-speed reduction mechanism for a flat display apparatus. The rotation-speed reduction mechanism comprises a position adjusting mechanism that includes one or more means for securely attaching a stand and a main body unit of the apparatus to one another, and a position adjusting means for adjusting the mounting position of the stand and main body unit. The rotation-axle bearing mechanism comprises a radial bearing and a thrust bearing for supporting a rotation axle between a display screen unit and the stand. The rotation-speed reduction mechanism reduces the speed of rotation between the display screen unit and the stand upon application of a rotation load exceeding a certain level.

A support structure includes a base, a pair of stands, a top hinge, and a pair of holding arms. The stands are rotatably connected to one end of the base to support the base. The top hinge is rotatably connected to the other end of the base opposite to the stands. The rotation plane of the top hinge is perpendicular to the rotation plane of the stands. The holding arms are rotatably connected to the top hinge for holding an object at any desired angle.
