Abstract:
1. A bicycle component securing structure comprising: a shaft having a first end portion and a second end portion with a longitudinal axis extending between the first and second end portions; a head member having a recess with the first end portion of the shaft member at least partially disposed therein; a lever member having first and second attachment portions disposed on opposite sides of the head member and an operating portion extending from the first and second attachment portions away from the head member; and a pivot pin coupling the head member and the lever member to the first end portion of the shaft member, the pivot pin having a first non-circular end section non-rotatably mounted in a non-circular first mating hole of the first attachment portion such that the lever member and pivot pin rotate together about a pivot axis, a second end section received in a second hole of the second attachment portion, and a cam section disposed between the first and second end sections within the recess of the head member to longitudinally move the shaft member relative to the head member in response to movement of the lever member about the pivot axis, the first non-circular end section having a first maximum transverse width larger than a maximum transverse cam width of the cam section and the maximum transverse cam width of the cam section being larger than a second maximum transverse width of the second end section, the second end section of the pivot pin being retained within the second attachment portion of the lever member with an attachment that prevents torque of the second attachment portion of the lever member from being directly transferred to the second end section of the pivot pin from the second attachment portion of the lever member via the attachment.
