1. An optical unit comprising:
a reflection portion which reflects an incident light flux, which is made incident from outside, in a reflection direction toward an imaging element from an incident direction;
a movable body comprising the reflection portion;
a fixed body;
a movable mechanism which allows the movable body to move relative to the fixed body;
a gimbal mechanism comprising a first support portion which supports the movable body swingably about a first axis; and
a bearing mechanism which supports the gimbal mechanism swingably relative to the fixed body about a second axis intersecting a direction of the first axis;
wherein the gimbal mechanism comprises a rod-shaped frame portion, wherein a first part of the first support portion is attached to a first end of the rod-shaped frame portion, and a second part of the first support portion is attached to a second end of the rod-shaped frame portion;
a support shaft having a columnar rode shape is attached to a central portion of the rod-shaped frame portion, wherein the support shaft extends in a direction of the second axis and is connected to the bearing mechanism;
the support shaft is inserted into an insertion port of the bearing mechanism to permit the rod-shaped frame portion to swing relative to the fixed body, and a swing axis of the rod-shaped frame portion is in the direction of the second axis; and
the fixed body comprises a preload generating member, wherein the preload generating member comprises an elastic member configured to press an end portion of the support shaft along the second axis relative to the housing.
