Angle adjustment mechanism, desktop apparatus, and method for assembling angle adjustment mechanism

An angle adjustment mechanism comprising:

• a base member to which a display device is attached;
• a support member configured to support the base member from below and move up and down in conjunction with a rotation operation of the base member;
• a mount member having a rotation shaft rotatably connecting the base member;
• and
• a suppression member configured to suppress up-and-down movement of the support member by frictional force, the suppression member being formed of an elastic material and attached to the mount member, wherein
• the suppression member is provided with a hole into which a part of the support member is inserted, and the frictional force is generated between the suppression member and the support member in the hole, and
• the support member is configured to move up and down by sliding through a hole provided in the suppression member in association with a rotation operation of the base member, and to stop movement by the frictional force when the rotation operation of the base member stops.
