Abstract: A vehicle detecting sensor using microbending of optical fiber and a vehicle detecting device using the same are provided to improve durability of optical fiber because a core is not influenced in a microbending although a top plate is moved down. A vehicle detecting sensor(1) using a microbending of optical fiber comprises optical fiber(30), a bottom plate(20), and a top plate(10). The bottom plate has a first body(23), a plurality of first protrusions(21), and a first groove(22). The first protrusions are protruded from the first body, and are separately arranged each other. The first groove is formed on the first protrusion in order to load the optical fiber. The top plate has a second body(13), a second protrusion(11), and a second groove(12). The second protrusion is protruded from the second body. The second groove is formed in a bottom of the second protrusion in order to load the second protrusion on the optical fiber. The top plate is moved toward the bottom plate side by pressure of a top side.

Abstract translation: 提供使用光纤的微弯曲的车辆检测传感器和使用其的车辆检测装置，以提高光纤的耐用性，因为尽管顶板向下移动，但是芯不受微弯曲的影响。 使用光纤的微弯曲的车辆检测传感器（1）包括光纤（30），底板（20）和顶板（10）。 底板具有第一主体（23），多个第一突起（21）和第一凹槽（22）。 第一突起从第一主体突出，并且彼此分开布置。 为了加载光纤，在第一突起上形成第一槽。 顶板具有第二主体（13），第二突起（11）和第二凹槽（12）。 第二突起从第二主体突出。 第二槽形成在第二突起的底部，以将第二突起装载在光纤上。 顶板通过顶侧的压力朝向底板侧移动。
