Tank fixing apparatus

A tank fixing apparatus comprising:

• a first band and a second band adjacent to each other, each including a fixed portion that is fixed to a support member that supports a tank, a pressing portion that extends from the fixed portion and presses an outer periphery of the tank toward the support member, and a distal end portion that extends from the pressing portion and is not fixed to the support member;
• a first fixing portion and a second fixing portion that fix the fixed portions of the first and second bands to the support member, respectively;
• and
• a first urging portion and a second urging portion that urge the first and second bands so as to give pressing forces for the tank to the pressing portions of the first and second bands, respectively,
• wherein a direction of the first band extending from the fixed portion to the distal end portion is opposite to a direction of the second band extending from the fixed portion to the distal end portion.
