    • A lens barrel includes: a first optical element group that has an optical element disposed on a first optical axis; a second optical element group that has an optical element disposed on a second optical axis extending along a direction different from a direction along which the first optical axis extends; and a bending portion disposed between the first optical element group and the second optical element group, that bends image light having passed through the first optical element. At least part of the first optical element group can be housed inside a first space formed as the bending portion moves further away from the first optical axis.
    • 镜筒包括:具有设置在第一光轴上的光学元件的第一光学元件组; 第二光学元件组,其具有设置在沿与第一光轴延伸的方向不同的方向延伸的第二光轴上的光学元件; 以及设置在所述第一光学元件组和所述第二光学元件组之间的弯曲部,其弯曲穿过所述第一光学元件的图像光。 第一光学元件组的至少一部分可以容纳在由弯曲部分进一步远离第一光轴移动而形成的第一空间内。
