Disclosed herein is a high-rigidity recliner for a vehicle. The recliner comprises an upper actuating member fixedly attached to a lower fixing member connected to a seat fixing base, and a lower actuating member fixedly attached to an upper fixing member provided to fix a back of a seat. The upper actuating member has a pair of first symmetrical supporting members and a pair of second symmetrical supporting members for supporting a cam and first and second lock gears, and an actuating pin guiding hole formed therethrough. The lower actuating member has an inner receiving section and an outer receiving section. The lower actuating member is in surface contact with the upper actuating member. Between the upper actuating member and the lower actuating member is fixedly interposed an actuating cam, which is fitted on the circumference of a shaft. The first and second lock gears are fixedly interposed between the lower actuating member and the actuating cam. The first and second lock gears have outer gear parts disposed in the inner receiving section of the lower actuating member, first supporting member contact surfaces, second supporting member contact surfaces, first cam contact surfaces, and second cam contact surfaces, respectively. The first and second lock gears lock or release the lower actuating member by rotation of the actuating cam. The outer gear parts of the first and second lock gears are formed by means of blanking. The inner gear part is integrally formed with the lower actuating member by means of blanking so that the inner receiving section and the outer receiving section are partitioned by the inner gear part. The high-rigidity recliner according to the present invention is characterized by the pair of the symmetrical lock gears fixedly interposed between the cam and the lower actuating member, the outer gear parts of the lock gears being engaged with the inner gear parts, respectively, whereby any clearances between the outer gear parts and the corresponding inner gear parts are eliminated and any irregular engagement of the outer and inner gear parts is prevented. Furthermore, the high-rigidity recliner according to the present invention has a simple structure, which reduces the number of the parts, whereby not only the time for assembly is reduced, but the cost for manufacturing the recliner is reduced as well. Particularly, the outer gear parts of the lock gears is formed by means of blanking so that the outer gear parts have high strength, whereby the durability of the recliner is improved.
