In this state, the second arm 20 is stopped at an arbitrary position of the first arm 10, the second arm 20 is rotated at that position, and the angle of the second arm 10 with respect to the installation surface 60 is set to an appropriate angle, and then the knob is picked. 52, the cam plate 51P is rotated, one cam portion 51 is pressed against the contact surface of the slide lock piece 30, the tightening shaft 58 is moved in the pulling direction, and the rotation lock piece 40 is pulled toward the first. The distal end portion 15 of the arm 10 and the proximal end portion 23 of the second arm 20 are sandwiched.

  Then, the engaging groove 39a of the parallel uneven groove band 39 of the slide lock piece 30 is engaged with the engaging groove 19a of the parallel uneven groove band 19 of the first arm 10 to prevent the first arm 10 from moving in the longitudinal direction. At the same time, the radial engagement groove 48a of the radial concave / convex groove ring 48 of the rotation lock piece 40 meshes with the radial engagement groove 28a of the radial concave / convex groove ring 28 of the second arm 20, and prevents the rotation of the second arm 20 at that point. And fix the setting angle. The rotation-preventing flat surface portions 58c formed on both side surfaces of the tightening shaft 58 are formed from the through long hole 11 to the protruding end 58a, and the tightening shaft 58 slides freely through the through long hole 11 but does not rotate. It is like that. Therefore, when the parallel concave and convex groove bands 19 and 39 are engaged with each other, the rotation lock piece 40 implanted with the tightening shaft 58 in a non-rotating state and the base end portion 23 of the second arm 20 are integrated with each other. Therefore, the non-rotation of the flat portion 58c of the tightening shaft 58 ensures that the arms 10 and 20 are locked at this position.

  Lastly, the article attachment piece 70 is also formed between the opposing surfaces of the rotation lock piece 80, the attachment arm 71 of the article attachment piece 70, and the distal end portion 21 of the second arm 20 when the tightening member 50c is loosened. The attachment arm 71 freely rotates in the vertical direction with respect to the second arm 20 in a state where the gaps are empty and the meshing is released. In this state, the mounting arm 71 is rotated and the angle of the mounting arm 71 with respect to the installation surface 60 is set to an appropriate angle. Then, the cam plate 51P is rotated by holding the knob 52, and one cam portion 51 is moved to the slide lock piece 30. The pressing arm 59 is pressed to move the tightening shaft 59 in the pulling direction, the second arm 20 is pulled and the mounting arm 71 is sandwiched between the distal end portion 21 of the second arm 20.

  As a result, the radial engagement grooves 78a of the radial uneven groove ring 78 on both surfaces of the mounting arm 71 correspond to the radial engagement grooves 28a of the radial uneven groove ring 28 of the second arm 20 and the radial uneven groove ring 88 of the rotary lock piece 80. It meshes with the radial engagement groove 88a and is securely locked at this position.

  Since the mounting dowel 73 is screwed into the screw hole 73b of the mounting dowel 73 with a certain amount of resistance via the washer 75 by the mounting screw 76 as described above, if it is forcibly rotated, the dowel body The radial engagement groove 77a of the radial concave / convex groove ring 77 provided on the bottom surface of 73a is engaged with and disengaged from the radial engagement groove 77a of the radial concave / convex groove ring 77 of the piece main body 70a and fixed at a predetermined position. The fixing of the mounting dowel 73 is normally performed after the article holding base P is fixed, but may be performed before fixing. Then, after the article holding table P is fixed at a desired position (or before), the vehicle-mounted article M such as a mobile phone or a smartphone is fixed to the article holding table P. In addition, when loosening, it should just be brought down with the fastening member 50 and the non-cam part 51h may come to the press part of each site | part. Then, the above-described operation is performed to reset the in-vehicle article M at a preferred position. By using the above-described cam structure as the tightening member 50, one-touch fixing / release is possible.
