DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an example of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of the device with the lid (2) opened, as viewed obliquely from above, and FIG. 2 is a side cross-sectional view of FIG. The cabinet (1) is provided with a concave surface (10) having an open upper surface, and the opening of the concave surface (10) is covered by a lid (2) pivotally supported by the cabinet (1). As in the prior art, the pivot portion (20) of the lid (2) has a shaft (11) protruding from the inner wall of the concave surface (10) and a hole formed in the side surface of the lid (2).
(21) (see FIG. 2). In the concave surface (10),
As before, the turntable (4
Mechanism block with (0) and pickup (41)
(4) is deployed. For convenience of explanation, the illustration of the turntable (40) and the pickup (41) is omitted in FIGS.

In the vicinity of the pivot of the lid (2), a sub-chassis
At the end of (42), there is provided a torsion spring (3) protruding two leg pieces (31) and (32) from the winding diameter portion (30), and the torsion spring (3) is provided.
The first leg piece (31) is in contact with the stopper (13) of the cabinet (1), and the second leg piece (32) is a holding piece located on the back surface of the lid (2).
Fits in (5). FIG. 6 is a view of the holding piece (5) as viewed from the direction B in FIG. 1. The holding piece (5) has a fitting groove at the center in the width direction.
(50) are formed, and both sides of the fitting groove (50) form oblique end surfaces (51) and (51) extending obliquely upward. Concave surface (10) shown in FIG.
A notch (12) is provided on the inner wall of the notch, and the notch (12) is formed by connecting a small hole (12b) to the shaft (11) side of the upper end of the large hole (12a) extending forward and backward. I have. As will be described later, when the lid (2) is attached, the second leg (32) of the torsion spring (3) once hooks on the side edge of the small hole (12b). At one end of the lid (2), a release protruding piece (22) in contact with the second leg (32) hooked on the notch (12) protrudes downward. The holding piece (5) is formed slightly lower than the release projection piece (22).

(When the lid is attached) The lid (2) is a cabinet.
(1) is attached in the following procedure. First, the torsion spring
The winding diameter part (30) of (3) is placed at the end of the sub-chassis (42), the first leg piece (31) is brought into contact with the stopper (13), and the tip of the second leg piece (32) is placed in FIG. As shown by the alternate long and short dash line in FIG. FIG. 3 is a rear view of FIG.
2) is elastically deformed laterally and fits into the notch (12). Next, the shaft (11) of the cabinet (1) is fitted into the hole (21) of the lid (2). The torsion spring (3) is in contact with the stopper (13) and the notch (12) to restrict the return of the torsion and is not yet in contact with the lid (2). With the lid (2) open, the release projection (22) overlaps the second leg (32).

When the lid (2) is closed by hand, the release projection piece (22) comes into contact with the second leg piece (32), as shown by a dashed line in FIG.
Push the second leg (32) downward. Second leg piece (32) and small hole (1
The hook with the side edge of 2b) comes off, and the second leg (32)
Escape to (12a). The second leg 32 returns to bend, that is, rotates counterclockwise as shown by arrow C in FIG. When the torsion spring (3) is in a natural state, the second leg piece (32) is the holding piece (5).
As shown in FIG. 5, the second leg piece (32) flexes and returns to face the fitting groove (50). Further, the torsion spring (3) is disengaged from the notch (12), so that the second leg (32) rotates in the opening direction. Accordingly, the second leg piece (32) is provided on one inclined end surface (51) of the holding piece (5) (see FIG. 6)
And fit into the fitting groove (50). This allows the torsion spring
The attachment of (3) to the lid (2) is completed. Since the holding piece (5) is formed slightly lower than the release projection piece (22), the second leg piece (32) comes into contact with the outer surface of the holding piece (5) when the second leg piece (32) returns to the bent state. Therefore, there is no fear of not fitting into the fitting groove (50).

In this embodiment, a torsion spring is attached to the lid (2).
To attach (3), the second leg (32) may be hooked once on the notch (12), and then the lid (2) may be closed. Since the step of removing the leg piece (32) from the claw piece (18) (see FIG. 8) is not required as compared with the related art, the workability of attaching the torsion spring (3) is improved,
You can save time and effort. In addition, conventionally, nail pieces
There was a case where the second leg piece (32) was hooked and left on (18) and the attachment of the second leg piece (32) to the lid (2) was forgotten. There is no such fear. Furthermore, conventionally, when the lid (2) is opened and the disc is not mounted on the turntable (40), the nail pieces (18) are exposed and the appearance is poor. However, in this example, the torsion spring
Since the second leg (32) of (3) is attached to the notch (12) of the cabinet (1), the appearance when the lid (2) is opened without the nail (18) is also improved.

A locking mechanism (not shown) is provided at the tip of the lid (2), and the lid (2) is locked to the cabinet (1) when the lid (2) is closed. In the above example, the pivot (20) of the lid (2) is connected to the axis of the cabinet (1).
(11) is fitted in the hole (21) of the lid (2),
A hole (21) is opened in the cabinet (1), and a shaft (11) is formed in the lid (2).
May be provided. Further, in this example, a disk reproducing device has been illustrated as an example of the electric device. However, another electric device that pivotally supports the lid, for example, a cassette deck may be used.

The description of the above embodiments is for the purpose of illustrating the present invention, and should not be construed as limiting the invention described in the appended claims or reducing the scope thereof. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made within the technical scope described in the claims.
