A stud locking tool is equipped with a first clip and a second clip for sandwiching a mounting member. The mounting member is mounted in a member to be mounted by locking the stud. The first clip has a hollow inner cylindrical portion inserted into a mounting hole of the mounting member. A first flange is located at one end of the inner cylinder portion, and a locking claw is formed inside the inner cylindrical portion and engages with a thread of the stud. The second clip has a hollow outer cylinder portion sized to surround the inner cylinder portion of the first clip. A second flange is located at one end of the outer cylinder portion. An engagement claw extends from the outer cylinder portion and engages the first clip. An inclined surface adjacent to the outer cylinder portion includes a stud guiding surface.

A buoyant fastener structure includes a body portion and a fastening element. The body portion has a rotation-preventing portion and a position-limiting portion. The fastening element has a position-corresponding rotation-preventing portion, a position-corresponding position-limiting portion and a fastening portion. The rotation-preventing portion and the position-corresponding rotation-preventing portion prevent each other from rotating. A rotation-preventing buoyancy level exists between the rotation-preventing portion and the position-corresponding rotation-preventing portion. The position-limiting portion corresponds in position to and limits the position of the position-corresponding position-limiting portion. Therefore, the body portion is coupled to a first object, whereas the fastening portion is coupled to or removed from a second object, so as for the first and second objects to be coupled together and separated, repeatedly and quickly. Furthermore, the second object coupled to the first object is movable on the fastening element to adjust the position of the second object.

A fastener assembly includes a first lock member including a plurality of radially extending ratchet teeth and a second lock member including a base portion and at least one tab extending axially from the base portion. The at least one tab has a proximal end joined to the base portion and a free end opposite the proximal end. The second lock member further includes a plurality of radially extending teeth on an inner side of the free end of the at least one tab. The second lock member is positionable between a locked configuration in which the plurality of radially extending teeth are configured to engage the plurality of radially extending ratchet teeth and an unlocked configuration in which the plurality of radially extending teeth are spaced from the plurality of radially extending ratchet teeth. The base portion and the at least one tab are a single piece.

The present invention may provide a motor including a housing, a cover which covers the housing, a stator disposed inside the housing, a rotor disposed inside the stator, a rotary shaft coupled to the rotor, a bearing disposed on the cover, and a nut which is coupled to the cover and which is in contact with an outer ring of the bearing, wherein the cover incudes a first pocket accommodating the bearing and a second pocket which is disposed above the first pocket and to which the nut is rotation-coupled, the nut includes a body disposed to be lower than an upper surface of the cover and including a screw thread and an extension portion disposed to be higher than the upper surface of the cover, the body incudes a protrusion protruding outward from the screw thread, and the second pocket includes a first groove in which the protrusion is positioned.

An anti-rotation device for a pair of threaded components includes a pair of ratchet interfaces and a spring element. A first ratchet interface and the spring element are movably disposed within a first threaded component, and a second ratchet interface is disposed at a mating end of a second threaded component. During relative rotation of the pair of threaded components, the ratchet interfaces engage, providing a resistance to the threaded components loosening that is greater than a resistance that the ratchet interfaces provide to the threaded components tightening. The anti-rotation device engages automatically upon relative rotation of the threaded components, and not as a separate step occurring after rotation. Additionally, the anti-rotation device may be especially useful in systems where various types of movement can cause the threaded components to loosen, and where visual access to the anti-rotation device is impeded.
