【考案の詳細な説明】 〔産業上の利用分野〕 この考案は工作に用いる鋸に関する考案で、鋸身にエン
ジニヤリングプラスチックで形成した柄を一体不離で係
着する鋸に関する考案である。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a saw used for machining, and relates to a saw in which a handle made of engineering plastic is attached to a saw blade so as not to be integrally separated.

がある。Conventional saws are assembled with a saw body and a handle made separately, and especially for those with a thin plate, such as sandwiches, which have a reverse U-shaped cross section for reinforcement. The body is engaged with the back of the saw blade to reinforce the saw blade and prevent it from breaking or bending. And this saw with a spine has a saw blade made of steel plate,
It consists of a soft-iron back metal and a wooden handle, and a barrel saw that engages the wooden handle with the back metal forcibly fitted to the back of the saw blade, and the base of the saw blade. There is an invention of a saw with a handle, which is sandwiched between the necks of a wooden handle and fixed with a tack, for example, Japanese Utility Model Laid-Open No. 56-24205.

ではないかと誤解をされるものである。In addition, there is a device of a spoon in which a plastic handle and a core are integrally formed. (Actual development 55-93
385) [Problems to be solved by the invention] Among the above-mentioned conventional ones, the one in which the saw blade is held by a reinforcing member such as a spine provided on the handle is a saw when the spine is attached to the saw blade. If the processing accuracy of both the body and the back metal is not good, the saw blade will be distorted when they engage with each other and the cutting edge will bend when cutting the object, making it difficult to cut accurately.
It is misunderstood that if the saw blade is directly shaft-fixed or screwed to the handle, the engagement is likely to be loosened and the engagement is loose, which is uncomfortable and not a defective product.

る。In addition, among those that form the handle with plastic,
The one in which the handle and the blade plate are integrally molded is like a saw and the saw blade holding part of the handle has a thin wall thickness. With this, the saw blade holding part has strength against bending at the core part. Is insufficient and the saw blade holder may be bent or broken during use, and the saw blade and the saw blade holder may not be sufficiently attached to each other. In view of the above problems, the present invention makes the engaging portion of the saw blade and the saw blade retaining portion of the handle portion durable in engagement between the saw blade holding portion of the handle and the core of the saw blade, and The purpose of the present invention is to provide a saw with accurate and reliable engagement that does not occur.

固なものとする。In this invention, the handle (1) and the saw blade holder (2) are integrally made of engineering plastic, and the saw blade (3) corresponds to the saw blade holder (2) of the handle (1). Since the part (3 1 ) is inserted and fixed, the saw blade (3) is held accurately and surely on the handle part (1). Moreover, the corresponding portion (3 1) the hole is of the saw body holding part (2) in the shank of the saw body (3) (1)
The ribs (5 1 ) are provided around the (5) and the through hole (5) so that the saw blade (3) can be distorted to the handle (1) without using a locking tool. It can be fastened without ribs, and the ribs (5 1 ) are through holes.
Being around (5), the rib (5 1 ) strengthens the corresponding part (3 1 ) with the saw blade holder (2) and makes the saw blade holder (2) of the handle (1) strong. In addition, the saw blade holder (2) and the saw blade (3) are firmly attached to each other.

のであれば実施例に限るものではない。Further, (1) is a handle portion formed of engineering plastic, (2) is a saw blade holding portion integrally formed with the handle portion (1), and its cross section is an inverted U-shape. The thickness of the saw blade holder (2) is about 1/4 of the thickness of the handle portion (1). The thickness of the saw blade holding portion (2) is not limited to that of the embodiment, and may be thicker or thinner. However, the point is that it can hold the saw blade. (3) is a saw blade, in the embodiment, the saw blade is a single-edged saw of the Edo mesh type, and the saw blade (3) is a portion of the handle portion (2) corresponding to the saw blade holding portion (2) ( 3 1 ) That is, the through hole (5) that is long in the oblique direction with respect to the saw tooth row in the part that engages with the saw blade holding part (2), and the outer side of the back surface of the saw blade (3) on the upper side of the through hole (5). Ribs projecting towards (5 1 )
And a rib (5 1 ) protruding toward the outside of the surface of the saw blade (3) on the lower side of the through hole (5). The corresponding portion (3 1 ) of the saw blade (3) is integrally formed with the saw blade holding portion (2) of the handle portion (1) by the engineering plastic in the mold. . Therefore through hole (5)
It is natural that the engineering plastic is interposed in the interior. Nao, although holes (5) in the embodiment is a long hole, may be the addition circular holes or rectangular holes, etc., also, the rib (5 1) projecting direction to another embodiment of the saw body ( counterpart in what may be one either sides of 3) (as long as it may be the reinforcement of the 3 1). The through hole (5) also has ribs (5) around the through hole (5).
1 ) can be projected, and it is also through hole by engaging with the saw blade holder (2).
The invention is not limited to the example as long as the engineering plastic can be placed in (5).
