Support assembly and keyboard apparatus

A support assembly comprising:

• a support rotatably disposed with respect to a frame;
• a repetition lever rotatably connected to the support via a flexible portion;
• a spring element supported by a spring support portion fixed to the support, the spring element providing a rotational force to the repetition lever;
• and
• a contact portion between the repetition lever and the spring element,
• wherein a rotating portion of the repetition lever is provided with respect to the spring support portion on a side opposite to the contact portion between the repetition lever and the spring element,
• the contact portion includes a protrusion projecting from the repetition lever, the protrusion making contact with the spring element,
• the rotating portion including a rotation center on the flexible portion of the repetition lever, and
• when the support rotates away from the frame and the repetition lever rotates toward the support, the spring support portion is displaced between the contact portion and the flexible portion toward the flexible portion from the contact portion.
