Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is to superimpose an upper blade member and a lower blade member in a mounting groove of a holder so that a predetermined gap is formed between the blade members. The present invention relates to a T-type razor that is held by sandwiching it.

(Prior Art) Conventionally, in a T-shaped razor in which both upper and lower blades are sandwiched and held in a mounting groove, a spacer is interposed between an upper blade and a lower blade that overlap with each other, thereby vertically moving the blade. There is one in which a gap is formed between both blades. Further, at least one of the upper and lower blades is formed into a blade having a thick mounting portion and a thin blade portion, and the spacer portion is formed by the thick mounting portion fitted in the mounting groove. There was also one that was configured.

(Problems to be Solved by the Invention) However, the former one, in which the spacer is interposed, has a problem that the number of parts is increased.

Also, in the latter case, since a metal plate having a uniform thickness as a whole is pressed or cut, not only the manufacturing process becomes complicated, but also the plate thickness of the processed portion becomes uneven, There is a problem that it is not possible to make a highly accurate blade body due to inconvenience such as roughened surface, and when the blade body is attached to the holder, there is a gap between the blade body and the mounting groove of the holder. However, there is a problem in that they cannot be reliably assembled.

Configuration of the Invention (Means for Solving the Problems) Therefore, in order to solve the above problems, the present invention has at least one of the upper and lower blades having a thick portion and a thin portion. And, it is composed of a cut piece of a deformed plate having high plate thickness accuracy and surface finishing accuracy, and the thick part of the cut piece constitutes a spacer part for forming a gap, and the thin part of the cut piece is formed. The means for forming the blade portion of the blade body is adopted.

(Operation) That is, when the upper and lower blade bodies are overlapped with each other, a predetermined gap is formed between the blade bodies by the spacer portion of at least one of the blade bodies. Then, by inserting the double blades into the mounting groove of the holder while the double blades are superposed, the upper and lower blades are surely assembled to the holder.
