アリング径に合わせる必要がある。 Therefore, in order to properly fit the bearing, it is necessary to perform post-processing of the hole machining to remove the dimensional difference due to the slope and match the inner diameter of the bearing locking hole to the bearing diameter.
そこで、本考案のウオータポンプボデーでは、
このような後加工処理の必要を無くすことを技術
的課題とする。 Therefore, in the water pump body of this invention,
A technical challenge is to eliminate the need for such post-processing.

(Means for solving the problem) The technical means taken to achieve the above-mentioned technical problem was to press-form the main member with a metal material to form a stepped cavity, and to form a stepped cavity. A bearing is press-fitted into the cavity, and a sub-member is press-molded into a substantially concave shape from a metal material, and the sub-member is press-fitted into the stepped concave cavity of the main member, and the bottom surface of the sub-member is press-fitted. In addition to holding the bearing, a mechanical seal is fitted into the sub-member, which is approximately in the shape of a cup.
（作用）
本考案による主部材はプレス成形によつて形成
されているので、ベアリングが圧入される段付凹
腔部は、その内径を一様に同一径に仕上げること
ができる。それゆえに、従来装置に見られたよう
な中子の抜け勾配による寸法差は発生しない。(Function) Since the main member according to the present invention is formed by press molding, the stepped concave portion into which the bearing is press-fitted can be finished to have the same inner diameter. Therefore, dimensional differences due to the draft angle of the core as seen in conventional devices do not occur.
また、圧入された副部材により、主部材に嵌入
されるベアリングの位置決めがなされ得る。 Further, the press-fitted sub-member allows positioning of the bearing to be fitted into the main member.

手順が非常に楽になる。このことは製作およびコ
スト面等での合理化に役立つ。 With this configuration, there is no need for back hole machining in conventional equipment, and in addition, bearings and mechanical seals can be assembled accurately and easily, making the procedure extremely easy. This is useful for streamlining production and costs.
（実施例）
以下、この考案の実施例について、添付図面を
参照して説明する。(Example) Hereinafter, an example of this invention will be described with reference to the accompanying drawings.
図において、１と２は、ウオータポンプボデー

でもない。 In the figure, 1 and 2 are a main member and a sub-member (hereinafter simply referred to as the main or sub-member) of the water pump body, and both are press-worked metal parts, and the sub-member 2 has a roughly round cross section. shape, and is press-fitted into the stepped portion of the concave cavity 1a of the main member. 3 is a rotating shaft, 4 is a bearing, and 5 is a drive side pulley bracket. Thus, one end surface (right side in the drawing) of the bearing 4 is fitted and positioned on the outer bottom surface of the sub-member 2. 6 is a mechanical seal, rotating shaft 3
Needless to say, it is fitted into the sub-member 2 at the top to seal the concave cavity 1a and the direction toward the bearing section.
