A stand, comprising:

• an elongated member to which an item is attached;
• a base to which a lower end of the elongated member is fixed;
• legs openably attached to the base;
• and
• leg opening angle changing members configured to change opening angles of the respective legs, wherein
• the base includes leg attaching portions to which proximal ends of the respective legs are attached,
• each leg opening angle changing member includes:
• an insertion portion arranged between the leg attaching portion and the proximal end of the leg;
• and
• an attachment portion attached to the leg attaching portion or the proximal end of the leg,
• each leg opening angle changing member is attached to the leg attaching portion or the proximal end of the leg by means of the attachment portion, and
• each leg opening angle changing member is configured to change the leg opening angle to an opening angle smaller than an opening angle of the leg in a fully opened state by arranging the insertion portion between the leg attaching portion and the proximal end of the leg in a state in which the leg opening angle changing member is attached to the leg attaching portion or the proximal end of the leg.
