In one example of the joint, the joint further includes a pin that joins the main body portion and the tip portion.

In one example of the joint, the joint portion joins the main body portion and the tip portion by means of mechanical joining and chemical joining.

According to the above-described joined product, since the body portion and the distal end portion are joined by chemical joining in addition to mechanical joining, the strength of the joined portion is further improved.

In one example of the joint, the tip portion includes a hard material.

According to the above-described joint, the wear resistance of the tip portion is improved.

In one example of the joint, the tip portion includes a sintered body.

In one example of the joint, the elastic modulus of the distal end portion is greater than the elastic modulus of the main body portion.

According to the above-mentioned joint, the tip portion is not easily deformed.

In one example of the joint, the distal end portion is configured to act on the object while being moved relative to the object.

According to the above-described joint, the tip end portion favorably acts on the object that moves relatively.

In one example of the joint, the tip end portion and the body portion include a thin plate.

According to the above-described joint product, deformation of the joint product due to heat is less likely to occur than in the case where the main body portion and the distal end portion are joined by metallurgical joining, for example.

In one example of the joint, the tip end portion and the body portion include a post.

According to the above-described joint, since the main body portion including the column and the tip portion including the column are joined by mechanical joining, the main body portion and the tip portion can be joined easily, as compared with a case where the main body portion and the tip portion are joined by metallurgical joining, for example.

In one example of the joint, a jig for supporting the object is included.

According to the above-described joint, the object to be processed can be appropriately supported.

In one example of the engagement, the clamp includes a blade of a centerless grinding device.

As shown in fig. 1, the joint 10 includes a main body portion 100, a distal end portion 200, and a joint portion 20. The main body 100 is, for example, a column, a cone, a frustum, a sphere, or a regular polyhedron, or a solid similar to these. The tip portion 200 is, for example, a column, a cone, a frustum, a sphere, or a regular polyhedron, or a solid similar to these. The main body 100 and the distal end 200 are arranged in the arrangement direction, for example. The arrangement direction is, for example, a direction parallel to the first reference direction.

The relationship of the first material and the second material is illustrated by way of example. In a first example, the first material and the second material are different.

The first material of the body portion 100 includes, for example, a hard material and a general material. The general material is a material different from the hard material.

In a state where the body portion 100 and the distal end portion 200 are joined by the joining portion 20, the body interface 120 and the distal end interface 220 face each other.

In the arrangement direction, the direction in which the distal end portion 200 is separated from the main body portion 100 is referred to as a "first separation direction".

When a first load acts on the distal end portion 200, the joint portion 20 is configured to restrict movement of the distal end portion 200 with respect to the main body portion 100 in the first disengaging direction. The joint 20 receives the first load applied to the distal end portion 200 on the main body portion 100, thereby restricting the movement of the distal end portion 200 with respect to the main body portion 100 in the first disengagement direction.

When a second load acts on the distal end portion 200, the engagement portion 20 is configured to restrict movement of the distal end portion 200 with respect to the main body portion 100 in the second disengaging direction. The joint 20 receives the second load applied to the distal end portion 200 on the main body portion 100, thereby restricting the movement of the distal end portion 200 with respect to the main body portion 100 in the second disengaging direction.

According to the joint 10, since the main body portion 100 and the distal end portion 200 are joined by mechanical joining, deformation of the joint 10 due to heat is less likely to occur than, for example, the case where the main body portion 100 and the distal end portion 200 are joined by metallurgical joining. This contributes to the tip portion 200 acting well on the object.

In the second example, the object W does not move, and the joined object 10 moves relative to the object W. In the third example, both the joined object 10 and the object W move. The distal end portion 200 includes a contact surface 213 that contacts the object W. Contact surface 213 is included in upper surface 212.
