For example, the protruding portion 61 is arranged in a straight line extending through the center of the front wall portion 72 to reach the left and right edges.

  The guide groove 62 on the lock member 51 side includes a release-side engagement portion 62a with which the protrusion 61 engages when the fixed knob portion 56 is in the unlocked position (FIG. 12B), and a fixed knob portion 56. Is in the lock position (FIG. 12A) and is provided between the lock-side engagement portion 62b with which the projection 61 engages. As a result, the rotation range of the lock member 51 is the range in which the protrusion 61 on the lock restricting member 52 side engages with the guide groove 62, that is, the lock release position shown in FIG. 12B and the lock shown in FIG. It is regulated within a range of about 90 degrees between the positions.

  The guide groove 62 is provided with a shallow groove portion 62c having a groove depth shallower than other portions on the guide groove 62 at positions adjacent to the release side engaging portion 62a and the lock side engaging portion 62b. When the fixed knob 56 is switched from the unlocked position to the locked position, or from the locked position to the unlocked position, the protrusion 61 gets over these shallow grooves 62c and engages with the lock-side engaging part 62b and the release-side engaging part. It reaches the joint portion 62a and is held in the lock side engagement portion 62b and the release side engagement portion 62a.

  Further, a rib 77 is provided on the rear side of the lock restricting member 52 to engage with rotation preventing portions 75 and 76 described later. The ribs 77 are disposed along the back side of the front wall portion 72 so as to pass through the axis of the lock restricting member 52, and both end sides thereof are connected to the inner peripheral side of the cylindrical portion 71. Engaging grooves 75a and 76a of the rotation preventing portions 75 and 76 are engaged from the rear side in the vicinity of the portions. The rib 77 is arranged in a direction perpendicular to the arrangement position of the engaging claw 73 with respect to the axis of the lock restricting member 52, and is also perpendicular to the protrusion 61.

  The lock restricting member 52 is restricted not only to move backward in the mounting portion 47 but also to rotate as the engaging claw 73 engages with the engaging portion 53, but the lock restricting member 52 faces backward. However, a large force is applied to the rotation direction every time the lock operation and the lock release operation are performed. Therefore, in this embodiment, the engagement grooves 75a and 76a of the rotation prevention portions 75 and 76 are engaged from the rear side with the ribs 77 of the lock restriction member 52, thereby assisting the restriction of the rotation direction by the engagement claws 73. Even when a rotational force stronger than necessary is applied to the fixed knob 56, the lock restricting member 52 can be reliably prevented from rotating.

  Further, in the vicinity of the locking means 45a and 45b, the concave grooves 78 and 79 are provided in the front-rear direction corresponding to the fixed knob 56 in the periphery thereof. The knobs 78 and 79 that avoid the knob are, for example, concentric with the fixed knob 56 and have a larger diameter than the fixed knob 56 and are formed in the front-rear direction along the axis of the fixed knob 56. The gripping avoidance concave groove 78 on the upper lock means 45a side is formed on the peripheral wall portion 41a of the upper support frame 41, and the grip avoidance concave groove 79 on the lower lock means 45b side is provided on the upper surface of the speaker box 28 of the lower speaker 26. 28a is provided respectively.
