下、カバー（７）の取り付けについて説明する。The control circuit printed circuit board (3) is fixed by a pair of protrusions (4) provided on the terminal block portion (1) (second).
Figure). Further, in order to indicate the mode of the changeover switch (2) attached to the control circuit printed circuit board (3), a protrusion (6) engageable with a locking hole (5) provided in the terminal block (1).
A face plate (6) with a) is attached and covered on the upper surface. The face plate (6) is provided with a square hole (6b) so that the mode selector switch (2) can be switched. (Fig. 3). The upper surface is covered with a cover (7) shown in FIG. The cover (7) has a total of two pairs ((left and right in FIG. 1) of engaging holes (8) which are engageable with the terminal block portion (1). Fourth
It has a first protrusion (9) which is an engaged portion (on the left side and the right side in the figure), and is attached to the terminal block (1) by this. The attachment of the cover (7) will be described below.

When the cover (7) is engaged with the locking hole (8) of the terminal block (1), the two portions of the first protrusion (9) of the cover (7) (on the right side in FIG. 4) are located on the cover (7). It comes off due to plastic deformation.

（１）の第２の突起（11）とが係合する所で開状態を保
持することができる。The cover (7) in this state can be opened upward by drawing an arc as shown by the arrow in FIG. 2 with the engaging point as a fulcrum. However, when the cover (7) is opened upward, the state cannot be maintained due to the weight of the cover (7), which hinders the mode switching work. Therefore, in order to hold the cover (7) in an open state, as shown in FIG. 2, a second protrusion (11) is provided at the center of the terminal block portion (1), and one cover (7) is provided at the center. By providing the semicircular third protrusion (12) which is also the engaged portion, in the process of opening the cover (7),
The second protrusion (11) of the terminal block (1) and the third protrusion (12) of the cover (7) come into contact with each other, and the third deformation occurs due to plastic deformation of the terminal block (1) and the cover (7). The projection (12) rides over the corner of the second projection (11), rotates counterclockwise and engages with each other to hold the position of the cover (7). With this structure, when the cover (7) is opened beyond a predetermined position, the third protrusion (12) of the cover (7) and the second protrusion (11) of the terminal block portion (1) are engaged with each other. The open state can be maintained with.
なお、この位置は、カバー（７）の回転角度が約90°と
なるように、端子台部（１）の第２の突起（11）とカバ
ー（７）の第３の突起（12）との位置関係が決定されて

部（１）に取付けられている。At this position, the second protrusion (11) of the terminal block portion (1) and the third protrusion (12) of the cover (7) are arranged so that the rotation angle of the cover (7) is about 90 °. The positional relationship has been determined, and even in this state, the cover (7) is securely attached to the terminal block portion (1).

うにしてもよいことはいうまでもない。Therefore, since the cover (7) is maintained in the open state, the mode changeover switch (2) can be easily operated. After the mode changeover switch (2) has been switched, the cover (7) is pushed in the clockwise direction to plastically deform the terminal block portion (1) and the cover (7) so that the central projection of the terminal block portion (1) is deformed. The central third protrusion (12) of the cover (7) is disengaged from (11), and the cover (7) hits the upper surface of the terminal block portion (1) in an arc. Then, by further applying a force, the locking hole (8) on the right side (FIG. 1) of the terminal block portion (1).
The first protrusion (9) on the right side of the cover (7) is engaged with the first protrusion (9) of the cover (7) and the four locking holes (8) of the terminal block portion (1) as in the initial state. ) The cover (7) is securely attached to the terminal block portion (1) by the engagement at four locations. The pair of locking holes (8) on the notch (10) side and the pair of first holes
Since the projections (9) serve to hold the cover (7) so as not to open it, it goes without saying that one may be provided for each.

And the third protrusion is formed so that the engaging portion of the terminal block portion and the engaged portion of the cover and the second protrusion and the third protrusion engage with each other at a predetermined position. While the mounting structure is extremely simple, the inverted state of the cover can be maintained, so that the cover mounting structure of the control device can be obtained in which the operating portion can be operated without removing the cover.
