The side cover 6 swings around the swing shaft 34 by its own weight,
The side cover 6 opens to the open position. FIGS. 1 and 5 show a state in which the first side cover is opened. When the first side cover 6 is opened, the spool support 13 is exposed. In this state, when the finger is inserted through the opening 16a and the position of the slider 67 of the centrifugal brake mechanism 25 in the spool radial direction is switched, the braking force can be adjusted. That is, when the slider 67 is disposed on the inner peripheral side with respect to the locking projection 70b, the slider 67 cannot contact the brake liner 68, and the braking force is reduced accordingly.

When the first side cover 6 is opened, the spool support portion 13 is turned counterclockwise by pinching the operation protrusion 16 with a finger. Then, the spool support 13 is disengaged from the side plate 8, and the opening 8a is exposed to the outside. In this state, the spool 12 can be removed by pinching and pulling out the spool shaft 20. When the spool 12 is taken out and mounted again, the first side cover 6 is closed.

Further, the slide portion 85a is held between a lock release position shown by a solid line in FIG. 7 and a lock position shown by a two-dot chain line by a holding mechanism (not shown). The locking piece 85b is a metal plate member having elasticity. The base end is disposed along the swinging shaft 34, and the distal end is bent toward the swinging shaft and further has a chevron shape toward the locking disk 45. It is bent convexly. The tip bent in this chevron is divided into two so as to be able to straddle the swing shaft 34, and the protruding portion 85c of the chevron abuts on the left side surface of the locking disk 45 in FIG. At this time, the locking piece 85b bends elastically and urges the swing shaft 34 to the right in FIG. 7 via the locking disk 45, thereby holding the swing shaft 34 in the closed posture.

The form of the locking is not limited to the locking piece, but may be any form as long as the rocking shaft 34 can be held in the closed posture. [Embodiment 4] As shown in FIGS. 8 and 9, in addition to the first side cover 6, a spool supporting portion 13 may be mounted on the side plate 8 so as to be swingable. In the fourth embodiment, both are rocked around the same rocking shaft 34, but they may be rocked by different rocking shafts. Further, the first side cover 6 may be swung about an axis parallel to an axis orthogonal to the spool shaft 20 as shown in the second embodiment.

In FIGS. 8 and 9, the spool support 1
3 is mounted on the swing frame 90 so as to be rotatable and immovable in the axial direction. The swing frame 90 is a substantially raindrop-shaped plate-like member connecting two large and small circles, and has a circular opening 90a for mounting the spool support 13 in the large circle. A step portion 14 b is formed on the outer peripheral surface of the ring portion 14 of the spool support portion 13.
A retaining ring 92 is mounted adjacent to “b”. The opening 90a is fitted into the step portion 14b and the spool support portion 13
Are rotatably mounted on the swing frame 90. Step 1
A retaining ring 92 is mounted adjacent to 4b. The axial movement of the spool support 13 at the opening 90 is restricted by the retaining ring 92. A boss 90b through which the swing shaft 34 penetrates is formed in the small circle portion. A boss portion 90b is rotatably mounted on the penetrating portion, and the swing frame 90 is swingably supported by the swing shaft.

As in the first embodiment, a screw portion 34a to be screwed into the screw hole 33a is formed at the tip of the swing shaft 34, and the large-diameter tool engaging portion 3 is adjacent to the screw portion 34a.
4b is formed. The screw portion 34a is provided on the cover body 3
3 screwed. Boss portion 90b and tool engagement portion 34
A coil spring 35 is mounted on the outer peripheral side of the swing shaft 34 in a compressed state between the coil spring 35 and b. The coil spring 35 is a member for urging the first side cover 6 outward similarly to the first embodiment.

A pipe member 36 is disposed concentrically on the outer peripheral side of the swing shaft 34 adjacent to the boss portion 90b, penetrating the side plate 8. The tip of the swing shaft 34 is rotatably supported by the pipe member 36, the base end is rotatably supported by the side plate 9, and further projects outward from the second side cover 7.
The pipe member 36 rotatably supports the swing shaft 34 and supports the swing shaft 34 so as not to move in the axial direction. A large-diameter portion 36a is formed at the tip of the pipe member 36, and an O-ring 37 for regulating a swing speed is mounted in the large-diameter portion 36a.

A coil spring 94 is mounted between the large diameter portion 36a and the side plate 8 in a compressed state. This coil spring 9
Reference numeral 4 denotes a member for urging the swing frame 90 outward in the axial direction. A parallel chamfered portion 36b is formed on the outer peripheral surface of the pipe member 36 except for the large-diameter portion 36a, and an oval hole for supporting the chamfered portion 36b in the axial direction movably and non-rotatably on the side plate 8. A support member 38 having 38a is screwed. A restricting disk 39 for restricting the axial movement of the swing shaft 34 is fixed to the base end of the pipe member 36 at intervals by a retaining ring 39a. The first side cover 6 moves in the axial direction by the gap between the base end of the pipe member 36 and the regulating disk 39. By pinching the pipe member 36 between the regulating disc 39 and the large-diameter portion 36a after the movement of the first side cover 6, the swing shaft 34 is supported so as not to move in the axial direction with respect to the pipe member 36. In addition, this regulating disc 39
Abuts on the side plate 8, the axial position when the first side cover 6 is opened is determined. Thus, the first side cover 6 is attached to the side plate 8 so as to be swingable and movable in the axial direction by a predetermined distance, and can be opened and closed without falling off the side plate 8.

A screw portion 34 c is formed at the base end of the swing shaft 34, and the screw portion 34 c is screwed into a detachable nut 40. The detachable nut 40 is mounted on the second side cover 7 so as to be rotatable and immovable in the axial direction. When the detachable nut 40 is rotated counterclockwise to separate the screw portion 34c from the detachable nut 40, the swing shaft 34 is biased by the coil spring 35 and moves leftward in FIG. When the locking disk 45 contacts the pipe member 36, the pipe member 36 is in contact with the swing frame 90 and cannot move to the left, so the swing shaft 34 stops. Then, the cover body 33 also moves to the left, and the first side cover 6 opens. When the first side cover 6 is opened, it swings by its own weight. The swing speed at this time is regulated by the O-ring 37 to a slow speed. In this state, only the first side cover 6 opens.

Subsequently, the spool support 13 is rotated counterclockwise to remove the spool support 13 from the side plate. Then, at the time when it comes off, it is urged by the coil spring 94 and moves to the left until the regulating disc 39 comes into contact with the side plate 8.
In this state, the boss 90b moves to the outside of the side plate 8 and swings by its own weight. Here, since the two members are swingably supported by one swing shaft 34, the configuration of the support portion is simplified. Further, since the spool support 13 is not separated from the side plate 8, there is no possibility that the spool support 13 is lost.
