PROBLEM TO BE SOLVED: To provide a grip for a driver which can reduce volume and weight and is highly convenient in usage.SOLUTION: A grip 2 for a driver is composed mainly of a grip body 20. The grip body 20 comprises a fixed part 21 and a used part 22. Side portions 23, 24 are formed parallelly on both sides of the used part 22. The width diameter of the side portions 23, 24 is defined as X. Contact parts 25, 26 are formed between the side portions 23, 24, respectively. The width diameter of the contact parts 25, 26 is defined as Y. Here, Y≤3/4X. A fitting part 211 is formed at a top edge of the fixed part 21 of the grip body 20 in an axial direction. A driver bit 30 is inserted and fixed to the fitting part 211, or a plastic is formed by injection molding to cover the driver bit 30. A long axis center line of the grip body 20 and the driver bit 30 are parallel. A major diameter of the fitting part 211 is defined as Z. Here, Z≤1/2Y.SELECTED DRAWING: Figure 6 |
