Composite bicycle component, composite bicycle crank arm, and method for manufacturing composite bicycle component

摘要

A composite bicycle component comprises a first member, a second member, a bonding member, and an inner holding member. The first member is made of metallic material. The second member is made of non-metallic material. The first and second members are configured to form an interior cavity therebetween in a state where the first and second members are attached to each other. The bonding member is configured to attach the first and second members to each other. The inner holding member is configured to be disposed within the interior cavity so as to prevent the first and second members from being separated from each other until completion of attaching the first and second members to each other.

1. A composite bicycle component comprising:
a first member made of metallic material, the first member including
a first base portion,a first side wall portion extending from the first base portion, anda second side wall portion extending from the first base portion and being spaced apart from the first side wall portion in a first direction; a second member made of non-metallic material, the first and second members being configured to form an interior cavity therebetween in a state where the first and second members are attached to each other, the second member including
a second base portion spaced apart from the first base portion in a second direction perpendicular to the first direction,a third side wall portion extending from the second base portion and being provided between the first side wall portion and the second side wall portion in the first direction, anda fourth side wall portion extending from the second base portion and being spaced apart from the third side wall portion in the first direction, the fourth side wall portion being provided between the first side wall portion and the second side wall portion in the first direction, the interior cavity being provided only directly between the third side wall portion and the fourth side wall portion when viewed along the first direction; a bonding member configured to attach the first and second members to each other; a first connecting member disposed in the interior cavity and configured to be connected to a crank axle; a second connecting member disposed in the interior cavity and configured to be connected to a pedal; and an inner holding member configured to be disposed only within the interior cavity between the first connecting member and the second connecting member so as to prevent the first and second members from being separated from each other until completion of attaching the first and second members to each other.
