    • PROBLEM TO BE SOLVED: To provide an impeller for an agitator which can surely improve agitation efficiency, can agitate and knead uniformly, can rotate lightly, can lighten the loads on a hand agitator and its operator, can be easily handles, has a simple constitution, and is excellent in durability, suitable for mass production, low in cost, and economical. SOLUTION: An upper edge 42 is formed in a cone shape where the top part 44 of the upper edge is located at the highest position. The top part 44 of the upper edge is situated about three-fifths of the whole length from a base edge 40. An angle formed between the base edge 40 and a base end-side inclined upper edge 45 is made to be large. A position located about one-fourths of the whole length from the base edge 40 is made to be a strong twist starting part 47. The base end edge 40 is stuck in a state having a slight oblique angle 12 against the center axis of a rotating body 4. A part from the base end edge 40 to the strong twist starting part 47 is formed in a state having a gentle twist toward the oblique angle 12. A part from the strong twist starting part 47 to a tip edge 41 is formed in a state having a strong twist toward the oblique angle 12. COPYRIGHT: (C)2004,JPO
    • 要解决的问题:为了提供可以确保提高搅拌效率的搅拌器的叶轮,可以均匀地搅拌和捏合,可以轻轻地旋转,可以减轻手动搅拌器及其操作者的负载,可以容易地处理,具有 结构简单,耐久性优良,适合批量生产,成本低,经济。 解决方案:上边缘42形成为锥形,其中上边缘的顶部44位于最高位置。 上边缘的顶部部分44从基部边缘40位于整个长度的大约五分之三处。形成在基部边缘40和基端侧倾斜上边缘45之间的角度被制成较大。 位于从基部边缘40全长约四分之一的位置被制成强扭曲起始部分47.基端边缘40相对于旋转的中心轴线被卡在具有轻微倾斜角度12的状态 从基端40到强扭起始部47的部分形成为朝向倾斜角12的平缓扭转的状态。从强扭曲起始部47到前端41的部分形成为 对斜角12具有强扭曲的状态。(C)2004,JPO
