Shifting structure

A shifting structure comprising:

• a shift lever including a shift shaft extending in a vertical direction and a rod axially movably provided in the shift shaft;
• a shift knob provided on an upper end of the shift lever, the shift knob including:
• a button for moving the rod from a lock position to a lock release position and vice versa;
• a core having a tubular portion accommodating an upper end of the shift shaft and a button support portion actuatably supporting the button;
• and
• a cover ring provided on an outside surface of the tubular portion of the core and having a hole allowing the shift shaft to pass therethrough,
• wherein,
• the tubular portion of the core has an upper engagement part and a lower engagement part disposed at a lower position than the upper engagement part;
• the shift shaft has a lockable recess engaging the lower engagement part of the tubular portion of the core;
• and
• the cover ring includes:
• a main body having a tubular shape extending in the vertical direction;
• a plurality of main body lockable protrusions disposed inside the main body, each of the main body lockable protrusions extending up from a lower end of the main body and having a pawl on an upper end thereof, the pawl engaging with the upper engagement part of the tubular portion of the core, and each of the main body lockable protrusions being configured to move inward elastically
• the shift shaft has a sleeve that bears the lockable recess, with the lockable recess defining a hollow facing radially outward, and
• the tubular portion has a plurality of sections arranged in a circumferential direction of the tubular portion, each of the sections of the tubular portion having an elastic property that causes a lower end thereof to move inward and each section of the tubular portion bearing:
• the upper engagement part having a hollow facing radially outward and engaging with the pawls of the main body lockable protrusions of the cover ring,
• the lower engagement part having a projection protruding radially inward and engaging with the hollow of the lockable recess, and
• a temporary engagement part that is releasably engageable with the pawls of the main body lockable protrusions of the cover ring.
