ばらけたり傷付いたりするおそれがある。By the way, in the above-mentioned embodiment, the two ends of the connecting portions (3c) and (3c) of the horizontal deflection coil (3) are respectively connected to the respective half bodies (20a).
The horizontal deflection coil is fixed by engaging the hook part (20g) (20g) of the
Since the g) is widened and the connecting part is inserted, the wire of the horizontal deflection coil may be loosened or damaged.
以下に上記欠点を解消した第２の実施例について説明す
る。A second embodiment which solves the above-mentioned drawback will be described below.
本実施例における保持枠(21)の半体(21a)は第４図に示
す如くフック部(21b)は一端にしか形成されていない。In the half body (21a) of the holding frame (21) in this embodiment, the hook portion (21b) is formed only at one end as shown in FIG.
そして、組立はまず、一方の水平偏向コイル（３）を半

b)に係止されると共に他端は対向する他方の半体(21a)
のフック部(21b)に係止されるため、強固に位置決め固
定される。Next, as shown in FIG. 5, the halves (21a) and (21a) each equipped with the horizontal deflection coil (3) are integrated as in the first embodiment. In this state, one end of each horizontal deflection coil (3) (3) is attached to the hook part (21
The other half (21a) that is locked to b) and has the other end facing
Since it is locked to the hook portion (21b) of the, it is firmly positioned and fixed.
（ト）考案の効果 上述の如く本考案によれば、水平偏向コイルの取り付け
が簡単で且つ強固に行うことができる。(G) Effect of the Invention According to the present invention as described above, the horizontal deflection coil can be easily and firmly attached.
又、垂直偏向コイルを保持する保持片は水平偏向コイル
を保持する保持片に一体となって形成されているため、
水平偏向コイルの取り付け位置が保持枠にたいして偏位
しても、垂直偏向コイルの取り付け位置も同時に同方向
に偏位するため、両コイル間の相対的な位置のばらつき
は極めて小さくなり精度の良い偏向ヨークを得ることが
できる。Also, since the holding piece that holds the vertical deflection coil is formed integrally with the holding piece that holds the horizontal deflection coil,
Even if the mounting position of the horizontal deflection coil is deviated from the holding frame, the mounting position of the vertical deflection coil is also deviated in the same direction at the same time. You can get the yoke.
