The plug 101 and the receptacle 102 include a rotation mechanism R1 and a connection mechanism C1. The rotation mechanism R1 is a mechanism for relatively rotating the first object and the second object about the first rotation axis A1. The connection mechanism C1 is a mechanism for connecting the first object and the second object such that the first object and the second object can be relatively rotated about the second rotation axis A2. The connection mechanism C1 includes a mechanism for detachably connecting.

The first rotation axis A1 and the second rotation axis A2 are examples of the first rotation axis and the second rotation axis that intersect each other, and are orthogonal to each other.

Specifically, as shown in FIGS. 1 and 2, the plug 101 includes a connection unit 103, a rotation unit 104, and a plurality of moving bodies 105.

The connection portion 103 is a member that is connected to the receptacle 102 so as to be able to rotate relative to the receptacle 102 about the second rotation axis A2, and includes a first base portion 106 and a pair of shaft portions 107.

The first base 106 is a part where the rotating part 104 and the plurality of moving bodies 105 are housed, and includes a substantially cylindrical hollow. The first base 106 according to the present embodiment has a cylindrical shape with a bottom, and a through hole is provided at the bottom.

各々 Each of the pair of shaft portions 107 is a portion protruding along the second rotation axis A2. The pair of shaft portions 107 protrude toward the receptacle 102 from positions opposite to each other on the outer surface of the first base portion 106 via the first rotation axis A1.

一対 Each of the pair of shaft portions 107 according to the present embodiment is rod-shaped, and includes a fixed shaft portion 108, a movable tip member 109, and an elastic member 110.

The fixed shaft portion 108 is a portion that is fixed at a symmetrical position on the outer surface of the first base portion 106 via the first rotation axis A1 and includes a hollow extending along the second rotation axis A2. Fixed shaft portion 108 according to the present embodiment has a rod shape extending along second rotation axis A2, and includes a cylindrical hollow.

中空 The hollow of the fixed shaft 108 is open to the outside through a circular opening provided at the tip of the fixed shaft 108. The distal end of the fixed shaft portion 108 includes a portion protruding inward such that the diameter of the opening is smaller than the diameter of the hollow.

The movable tip member 109 is a member that constitutes the tip portion of the shaft 107, and moves along the second rotation axis A2 when at least a part thereof is disposed in the fixed shaft 108. A part of the movable tip member 109 enters and exits the inside and outside of the fixed shaft portion 108 through an opening at the tip portion of the fixed shaft portion 108.

The tip of the movable tip member 109 has a spherical surface. The proximal end of the movable distal member 109 includes a portion that protrudes outward, and is disposed in the fixed shaft 108.

(4) The protruding portion of the base end portion of the movable tip member 109 and the protruding portion of the distal end portion of the fixed shaft portion 108 constitute a locking structure for engaging and stopping each other. This prevents the movable tip member 109 from dropping out of the fixed shaft 108 through the opening at the tip of the fixed shaft 108.

The elastic member 110 is a member having elasticity, and pushes the movable tip member 109 in a direction toward the receptacle 102 along the second rotation axis A2. The elastic member 110 according to the present embodiment is a spring disposed in the fixed shaft portion 108, and pushes the base end of the movable tip member 109 in a direction toward the receptacle 102.

Thus, when the elastic member 110 pushes the movable tip member 109, the movable tip member 109 protrudes outward from the tip of the fixed shaft portion 108 when no external force is applied. When an external force against the force of the elastic member 110 is applied, at least a part of the movable tip member 109 that has protruded outside enters the fixed shaft portion 108.

The movable tip member 109 may be a pin having a curved end, a flat end, or the like, or may be a sphere.

The connecting portion 103 is preferably configured such that the movable tip member 109 and the elastic member 110 can be arranged in the fixed shaft portion 108. For example, the fixed shaft portion 108 is configured as a member different from the first base portion 106, and may be fitted to the first base portion 106 by a screw structure or the like.

The rotating unit 104 is a member that is connected to the first base 106 via a plurality of moving bodies 105.

The fitting portion 111 is a cylindrical portion having an outer diameter smaller than other portions of the rotating portion 104, and is fitted in the first base portion 106.

The plurality of moving bodies 105 are members for rotating the fitting portion 111 and the first base 106 with each other about the first rotation axis A1. Each of the plurality of moving bodies 105 according to the present embodiment is a sphere that is rotatably held between fitting portion 111 and first base 106. The moving body 105 may be, for example, a cylindrical roller.

In the present embodiment, the fitting portion 111 is loosely fitted to the first base 106 with the plurality of moving bodies 105 interposed. As described above, the first base portion 106, the fitting portion 111, and the plurality of moving bodies 105 are configured in the same manner as the radial ball bearing, and configure the rotation mechanism R1. That is, the connection unit 103 and the rotation unit 104 are connected via the rotation mechanism R1.

Note that the connection unit 103 and the rotation unit 104 may be connected to each other so as to be rotatable about the first rotation axis A1. For example, the connecting portion 103 and the rotating portion 104 may be connected in the same configuration as another bearing such as a thrust bearing.
