Abstract
Generally, a fishing reel utilizes a gear pair, and vibration caused by the gear pair engagement occurs when a handle of reel rotates. The vibration is transmitted to a tip of a finger via the handle. When this vibration is large, an angler feels uncomfortable. It is known that a rotational feeling in a fishing reel strongly depends on the amplitude of the mesh frequency of the gear pair. It has been confirmed that the rotational feeling changes when the rotational speed of a handle changes. In order to evaluate the rotational feeling, a vibration generating machine (Vibration Simulator) is developed to simulate the vibration in actual products. After verification of this simulator, the relationship between a rotational feeling in reel and transmission error is investigated with the simulator.
