摘要:
A thimble 61 formed with graduations 65 and numerals 67 on the outer circumference thereof at predetermined intervals is molded by double-color molding using two kinds of resin 62, 63 with different colors. After a molding product having the graduations 65 protruding outwardly on the outer circumference of a base tube 64 is formed of the resin 62, an outer skin 66 covering the outside of the base tube 64 except for the graduations 65 is formed of the resin 63. Thereafter, the numerals 67 is formed on the outer skin 66 by means of laser marking. Similarly, an outer sleeve is formed with graduations and numerals on the outer circumferential surface along the axial direction at predetermined intervals.

A main body 11 holding an anvil 21 at one end portion and a spindle 41 at the other end portion through an inner sleeve 31 is formed with a frame 12 which is made by placing a pair of the frame elements 14A and 14B, which are formed by bending process of metal plate, one upon the other to reduce weight while ensuring the rigidity. The outside of the frame 12 is covered with resin 13 to reduce the weight, enhance the rigidity, and prevent the influence caused by the heat of hand when the frame 12 is gripped.
