1. A mount apparatus, comprising:
a mount portion;
a plurality of claw portions to be used for coupling by a bayonet coupling method;
a plurality of terminals that are disposed following a circumferential direction of the mount portion, and that are used for electrical connection;
a holding member configured to hold the plurality of terminals; and
a biasing unit configured to bias another claw portion which is engaged with a first claw portion of the plurality of claw portions in a direction parallel to a center axis of the mount portion,
wherein the holding member has a first tier and a second tier, where positions of holding the plurality of terminals differ in the direction parallel to the center axis,
wherein, among the plurality of terminals, the number of terminals held at the first tier is greater than the number of terminals held at the second tier,
wherein, in a case of viewing the mount portion from the direction parallel to the center axis of the mount portion, the biasing unit is located along the first claw portion of the mount portion, within an angle range in the circumferential direction of the mount portion,
wherein, in a case of viewing the mount portion from the direction parallel to the center axis of the mount portion, among the plurality of terminals on the first tier, a first terminal included in the plurality of terminals on the first tier is disposed further from the second tier than other terminals on the first tier, and
wherein an angle range where the first terminal has been disposed overlaps an angle range where the biasing unit has been disposed in the circumferential direction of the mount portion.
