a movement member that moves the holding member in a first direction intersecting an optical axis; a first biasing member that biases the holding member in a second direction intersecting the optical axis; and a second biasing member that biases the holding member at least in a direction of the optical axis, wherein a movement portion of the movement member is provided on the holding member. ### Claim 2 (depends on 1) The lens device according to claim 1, wherein the movement portion is provided on an inner side of an outer contour of the holding member. ### Claim 3 (depends on 1) The lens device according to claim 1, wherein the movement member has a screw and a nut, and the movement portion includes the nut. ### Claim 4 (depends on 3) The lens device according to claim 3, further comprising: a fixing member, wherein the screw is rotatably fixed to the fixing member, and the nut is held by the holding member. ### Claim 5 (depends on 1) The lens device according to claim 1, further comprising: a restricting member that restricts a position of the holding member in the direction of the optical axis. ### Claim 6 (depends on 5) The lens device according to claim 5, wherein a plurality of the restricting members are provided, and the plurality of restricting members are arranged in a direction around the optical axis. ### Claim 7 (depends on 5) The lens device according to claim 5, wherein the second biasing member is disposed at a position corresponding to the restricting member. ### Claim 8 (depends on 5) The lens device according to claim 5, further comprising: a fixing member, wherein the restricting member is loosely inserted into the fixing member. ### Claim 9 (depends on 8) The lens device according to claim 8, wherein a loose insertion portion of the restricting member is a metal member. ### Claim 10 (depends on 9) The lens device according to claim 9, wherein the metal member is a shaft member. ### Claim 11 (depends on 1) The lens device according to claim 1, wherein the movement member includes a first movement member and a second movement member that moves the holding member in a direction different from a movement direction by the first movement member. ### Claim 12 (depends on 11) The lens device according to claim 11, wherein the first biasing member is disposed within a range of an angle formed by the first movement member and the second movement member, which is less than 180 degrees, as viewed from the direction of the optical axis. ### Claim 13 (depends on 12) The lens device according to claim 12, wherein the first biasing member is disposed on a bisector line of the angle as viewed from the direction of the optical axis. ### Claim 14 (depends on 12) The lens device according to claim 12, wherein an angle formed by the first movement member and the first biasing member as viewed from the direction of the optical axis is 30 degrees to 60 degrees. ### Claim 15 (depends on 12) The lens device according to claim 12, wherein the angle is a right angle. ### Claim 16 (depends on 11) The lens device according to claim 11, further comprising: a fixing member; and a restricting portion that restricts a position of the holding member in a direction around the optical axis with respect to the fixing member, wherein the restricting portion is provided on an opposite side of the optical axis from the first movement member. ### Claim 17 (depends on 16) The lens device according to claim 16, wherein the restricting portion is provided along a line connecting the first movement member and the optical axis as viewed from the direction of the optical axis. ### Claim 18 (depends on 1) The lens device according to claim 1, further comprising: a fixing member; and a restricting portion that restricts a position of the holding member in a direction around the optical axis with respect to the fixing member. ### Claim 19 (depends on 18) The lens device according to claim 18, wherein the restricting portion has an engagement portion formed on the fixing member, and an engagement target portion formed on the holding member and engaged with the engagement portion. ### Claim 20 (depends on 19) The lens device according to claim 19, wherein the engagement portion has a first protruding portion, and the engagement target portion has a second protruding portion that is in contact with the first protruding portion. ### Claim 21 (depends on 20) The lens device according to claim 20, wherein the second protruding portion extends in a direction intersecting a direction in which the first protruding portion extends.
