Abstract
An arm-shaped structure includes a pipe-shaped main body and an attachment interface joined to at least one end of the main body and securable to another component. At least a portion of the main body and the attachment interface is formed by resin containing a continuous reinforcement fiber. The main body and the attachment interface are joined to each other in a state where relative movement along a longitudinal axis of the main body and around the longitudinal axis is prevented in accordance with engagement between a recess provided in one of the main body and the attachment interface and a protrusion provided in the other one of the main body and the attachment interface.
Claims3
An arm-shaped structure, comprising:
- a tubular main body;
- and
- an attachment interface joined to at least one end of the main body and securable to another component,
- wherein the main body and the attachment interface are joined to each other in a state where relative movement along a longitudinal axis of the main body and around the longitudinal axis is prevented in accordance with engagement between a recess provided in one of the main body and the attachment interface and a protrusion provided in the other one of the main body and the attachment interface,
- wherein at least one of a periphery of the recess and the protrusion is formed by resin containing a continuous reinforcement fiber, and
- wherein at least a portion of the continuous reinforcement fiber is oriented in a center-axis direction extending along an inner surface of the recess and in a center-axis direction extending along an outer peripheral surface of the protrusion.
