Abstract
Disclosed are a method for manufacturing a crank for a bicycle by bonding structural members to each other with an adhesive comprising; a step for applying the adhesive in a line-like or dot-like form in correspondence with an intervention region of the adhesive; a step for disposing a fabric in correspondence with the intervention region of the adhesive; a step for expanding the adhesive applied in a line-like or dot-like form in the fabric; and a step for bonding the structural members to each other with the adhesive expanded in the fabric, and a crank for a bicycle manufactured by the method. When the crank for a bicycle is manufactured by bonding the structural members to each other with the adhesive, the adhesive can be applied easily at a high accuracy and a good repeatability, variations of application condition and amount of used adhesive can be suppressed, and variation in quality can be suppressed.
