Abstract: An embodiment of the present invention relates to a cylindrical secondary battery in which a positive electrode terminal is adhered and fixed to a cylindrical can by an insulating sheet, and thus sealing between the cylindrical can and the positive electrode terminal can be facilitated due to an increased contact area.

Abstract: The present invention relates to an angle adjuster for a snowboard binder; the angle adjuster for a snowboard binder according to the present invention comprises a fixation member that forms a first locking part on its plate face and has first projection pieces protruding at least from both sides of its upper edge to be fixed on the snowboard, a base that has a through hole formed on its center, whereinto the fixation member is inserted, a diaphragm that is respectively formed on both sides of the base in a vertical direction, first combination grooves that are formed in a vertical direction at least on both sides of the through hole so that the first projection pieces may be inserted thereinto, a binder that is assembled with the fixation member to enable its rotation along upper grooves whereby the first projection pieces move along the upper edge of the through hole of the base, and a coupling member assembled above said binder whereon is formed a second locking part that mates with the first locking part

Abstract: The present invention relates to a snowboard binding. The snowboard binding comprises: a base, a high back, a foot cover, a first wire, and a lever. The base comprises a plate attached to the snowboard, and side walls extending vertically from both sides of the plate. The high back is installed to pivot on the side wall in the rear of the base. The foot cover is installed at a distance from the upper front of the base. The first wire connects the high back to the base and foot cover. The lever is installed to pivot on the back of the high back and moves the foot cover as the length of the first wire connecting the lever to the high back varies depending on the pivot direction, wherein the first wire connected to the high back is connected to the side facing the pivot axis. Therefore, the foot cover and high back simultaneously fix the front and rear of boots as a result of the pivoting of the lever in the locking direction, and release of the lever is prevented.

Abstract: Disclosed is a device for tightening a shoelace, the device comprising a shoe main body formed with an opening and a tongue finishing an inside of the opening; a shoelace connecting opposite sides of the opening; a handle connected to at least one of shoelaces connecting the opposite sides of the opening; and a hook formed in rear of the shoe main body and holding the shoelace pulled by the handle.
