COUPLING ELEMENT FOR A MUSCLE-POWERED VEHICLE, COUPLER FOR A MUSCLE-POWERED VEHICLE AND COUPLING STRUCTURE FOR A MUSCLE-POWERED VEHICLE

Abstract

A coupling element used to connect a coupler to a vehicle body. The coupling element comprises a coupling element body located within the coupler. The coupling element body includes an outer surface, an inner surface defining a coupling element hole, an internal thread, a coupling element rotation limiter that restricts the rotation of the coupling element body relative to the coupler, and a coupling element press-fit section that is press-fitted into the coupler. The coupling element rotation limiter includes a projection or recess. The coupling element body includes a coupling element proximal end section and a coupling element distal end section located on opposite sides of the coupling element proximal end section. The coupling element press-fit section is located closer to the coupling element proximal end section than the coupling element rotation limiter.
