An elastic wire clip assembly includes a connection member and an elastic wire clip. The elastic wire clip includes at least one clamping section configured for clamping an object to the outer surface of a writing instrument or the like, at least one assembly section connected to an end portion of the clamping section, and at least one elastic transfer section connected to the assembly section. The elastic transfer section deforms when the clamping section is pressed outward from the outer surface of the writing instrument. A restoring elastic force from the deformed elastic transfer section counteracts the pressure. The elastic wire clip is formed by bending one steel wire. The connection member comprises a hanging wall and a blocking wall opposite the hanging wall to form a socket for receiving and retaining the elastic wire clip.

A writing instrument includes a shaft barrel and a grip provided at part of the shaft barrel. The grip has a cylindrically shaped inside shaft part and a cylindrically shaped outside shaft part arranged at the outside of the inside shaft part, thinner than the inside shaft part, and made of a nonviscoelastic plastic. A space part is provided between the inside shaft part and the outside shaft part.

A carpenter pencil clip device is disclosed that attaches onto an end of the pencil and onto a pant or shirt pocket. The carpenter pencil clip device comprises a body component that is configured to form around an edge of the pencil. The body component also comprises a protruding spring clip which secures the pencil to a user's pocket. Further, the body component is typically constructed using a malleable metal, such as aluminum, to tightly secure the obscure shape of the carpenter's pencil. Thus, the body component is bent and formed around the edge of the pencil and then clipped onto the user's pocket for storage and easy access.

The retractable container of the present invention includes a body which accommodates a receptor supported by a spring and a knob configured to deploy and retract the receptor. In the retractable container, the body accommodates the receptor and the spring therein, has an entrance formed on one side thereof and an insertion opening formed on the other side thereof, into which the receptor and the knob are inserted, and comprises a body cam integrally formed with the body and comprising a guide bar which extends from the body to be disposed adjacent to a side of the insertion opening, and the knob is configured to have a feature in which a knock operation part is formed integrally with a protrusion member which connects an extension part and a pressing part inserted into the insertion opening of the body, thus the guide bar of the body cam is moved to respond to a change in position of the knock operation part.

An attachment structure in a writing instrument, includes: a first component; and a second component configured to be fitted into a fitting hole provided at an end of the first component, the second component including: a small-diameter portion; and a large-diameter portion disposed in front of the small-diameter portion; and a first outer step portion disposed between the small-diameter portion and the large-diameter portion, the fitting hole including: a small-diameter hole portion; and an inner step portion disposed in front of the small-diameter hole portion, the small-diameter portion being fitted into or loosely fitted into the small-diameter hole portion, the first outer step portion coming into contact with the inner step portion, the small-diameter hole portion includes a barb portion protruding from the inner face of the small-diameter hole portion, the barb portion being deformable by contact with the small-diameter portion when the second component is fitted.

An axial cylinder extending in an axial direction along a center axis and a writing member disposed inside the axial cylinder. The axial cylinder has fiber-like protrusions protruding toward an outside in a radial direction from an outer circumferential surface of the axial cylinder, the plurality of fiber-like protrusions are provided side by side on the outer circumferential surface, and each of the fiber-like protrusions has a plurality of rib parts which extend in predetermined directions when viewed from the outside in the radial direction and which are disposed side by side in a width direction orthogonal to the predetermined directions and a step part which is disposed between rib parts adjacent to each other in the width direction or disposed at an end portion in the width direction of the rib parts and extends in a predetermined direction.
