The frictional force between the two can be reduced, good rotational operability can be obtained, and the wear of the seal ring can be reduced.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 to 3 show the configuration of an electronic apparatus according to an embodiment of the present invention. FIG. 1 is an overall three-dimensional view, FIG. 2 is an exploded three-dimensional view of the main part, and FIG. 3 is a longitudinal sectional view of the main part. It is. As illustrated, the electronic device 1 includes an electronic device body 2, a lens barrel 3, and a mount 4. The electronic device 1 is, for example, any one of a PDA, a mobile phone, a digital camera, and the like.

  As shown in FIG. 1, in the electronic device 1 of the embodiment, the device body 2 has a substantially rectangular parallelepiped shape, and a mounting hole 22 is provided in the upper end surface of the device body 2 as shown in FIG. A control mechanism (not shown) is provided, the lens barrel 3 is rotatably mounted, and is electrically connected to the inside of the apparatus main body 2 via an electrical connection line (wire) 23.

  The lens barrel 3 holds a lens which is not clearly indicated by reference numerals, and a photoelectric imaging module 32 is provided inside as shown in FIG. An annular groove 33 is provided on the end surface of the lens barrel 3 on the device body 2 side.

  As shown in FIGS. 2 and 3, the mount 4 is integrally and airtightly attached to the lens barrel 3 for dustproofing and waterproofing between the lens barrel 3 and the device main body 2. The mount 4 includes an annular main body 40 having a substantially cylindrical shape, and the annular main body 40 is rotatably attached to the electronic device main body 2 at one end portion 4a thereof. In addition, a cylindrical seat 41 that can be swivel coupled to the electronic device main body 2 is formed at one end portion 4 a of the annular main body 40.
