FIG. 5 shows a state in which 13 is brought into contact with the tapered portion 11 of the groove 9 and the bent portion 53 formed at the upper end of the leaf spring 40. In the state shown in FIG. 5, the arcuate convex surface of the upper bent portion 53 of the leaf spring 40 abuts on the lens barrel 13, and the upper end of the bent portion 53 does not abut on the cylindrical surface of the lens barrel 13 and is in a raised position. The bent portion 53 is formed as is. By further moving the lens barrel 13 to the lower part from this state, the leaf spring 40 is spread to the side opposite to the side having the mounting surface 21 of the case 1, and as a result, the lens barrel 13 is always pulled toward the mounting surface 21 side. Lens barrel with the mounting surface 21 in contact with
It is transferred to the bottom until 13 abuts the bottom surface 22.

Adjust the position in the direction. At that time, the lens barrel 13 is a leaf spring 40.
And the escape pieces 51, 52 are in contact with each other at a point A within the range indicated by the height dimension i, so that the optical axis l- of the lens barrel 13 is slid between the lens barrel 13 and the leaf spring 40. Position adjustment can be performed in the l direction. Regarding the joint portion between the lens barrel 13 and the leaf spring 40, as shown in FIGS. 7 and 8 which are another embodiment of the present invention, the lens barrel is provided at the central portion in the width direction of the leaf spring upper portion 50. The joining surface 54 that protrudes to the side where 13 is formed is formed.
It can also be configured to be joined to the lens barrel 13 at 54.
In this case, since the lens barrel 13 does not hit the both side portions of the leaf spring upper portion 50 in the optical axis l-l direction, the escape small pieces 51 and 52 can be omitted, and thus the shape of the leaf spring 40 can be changed. Can be easy. Also, by bending the leaf spring upper part 50 vertically to the side opposite to the side having the lens barrel 13,
The same effect as above can be expected when adjusting 13 in the direction of the optical axis l-l. In short, when the lens barrel 13 is inserted and attached, it is not necessary to provide the pair of small pieces 51, 52 if the both ends 55, 56 in the width direction of the leaf spring 40 are not contacted.
