の両端部が軸受へ支持されて回転される構成である。The rotating roller shown in FIG. 2 is manufactured by attaching a piece 12 to a Tsuquibu 10, passing the shaft 14 through the piece 12 into the pipe 10, and fixing the shaft 14 and the pipe 10 with a set screw 16.
Both ends are supported by bearings and rotated.

必要があり、コスト高であった。However, with this structure, problems occur such as the set screw 16 loosening due to vibrations during rotation, causing relative rotation between the shaft 14 and the pipe 10, or displacement of the piece 12, resulting in poor rotation. Furthermore, in order to prevent the occurrence of rust, the shaft 14 must be made of a highly corrosion-resistant material such as stainless steel, resulting in high costs.

０とが相対回転したり、コマ１２がずれたりして回転不
良となることはない。The rotating roller shown in FIG. 3 is manufactured by insert molding a shaft 14 into a piece 12 and fixing the piece 12 to a pipe 10 by adhesive, and the shaft 14 is rotated while being supported by a bearing. In this case, since the shaft 14 is insert-molded into the piece 12 and the piece 12 is fixed to the pipe 10 by adhesive, the shaft 14 and the pipe 1 may be damaged due to vibrations during rotation as described above.
0 will not rotate relative to the top 12, or the top 12 will not shift, resulting in poor rotation.
しかし、この構造にあってはコマ１２へのシャフト１４
のインサート部分が少なく、シャフト１４のコマ１２か

Since the insert portion is small, in order to prevent the shaft 14 from falling off from the piece 12, it is necessary to perform special processing on the shaft 14, such as providing a groove in the shaft 14.
また、第２図に示される回転ローラと同様に錆の発生を
防止するためにシャフト１４をステンレス等の耐蝕性の
高い材料で形成する必要がある。Furthermore, like the rotating roller shown in FIG. 2, the shaft 14 must be made of a highly corrosion-resistant material such as stainless steel to prevent rust from forming.

の接触部となっている。The support body 26 has a main body formed in a cylindrical shape with a bottom, is inserted into the hollow part of the pipe 24 from the opening side of the main body, and is fixed to the pipe 24 by adhesive, and the bottom of the main body is flush with the axial end surface of the pipe 24. It is located above and serves as a support for the shaft 28. The support body 26 accommodates the end of the shaft 28 on the support side to the bearing 22 at the bottom of the main body, and
A shaft portion 26A that seals the shaft portion 8 is coaxially formed and serves as a contact portion with the bearing 22.
この支持体２６は合成樹脂製で、射出成形により成形さ

っている。The support body 26 is made of synthetic resin and is molded by injection molding, and the shaft 28 is made of metal and is integrally formed with the support body 26 by insert molding or press fitting. Note that the end of the shaft 28 on the opposite side from the receiving part in the shaft part 26A protrudes into the main body part and serves as a holding part when molding the support body.
上記構成によれば、シャフト２８は支持体２６の軸部２
６Ａにより密封されて錆の発生が防止される。特に現像
液等の液中において使用しても、シャフト２８が液内に
浸漬されることがなく、錆の発生を確実に防止できる。According to the above configuration, the shaft 28 is the shaft portion 2 of the support body 26.
6A to prevent rust from forming. In particular, even when used in a liquid such as a developer, the shaft 28 is not immersed in the liquid, and rust can be reliably prevented.
したがって、錆の発生を防止するためにシャフト２８を
耐蝕性の高い高価な材料、例えばステンレスで形成する
必要がなく、安価な耐蝕性の低い材料で形成でき、コス
ト安となる。Therefore, the shaft 28 does not need to be made of an expensive material with high corrosion resistance, such as stainless steel, in order to prevent the occurrence of rust, but can be made of an inexpensive material with low corrosion resistance, resulting in lower costs.
また、シャフト２８を支持体２６へのインサート部分が
多く、特別な加工を施すことなく、脱落しないように支
持体２６と確実に固定でき、コスト安となる。Further, since the shaft 28 has many inserts into the support 26, it can be securely fixed to the support 26 without any special processing so as not to fall off, resulting in lower costs.
