For example, the through hole 213 is formed to penetrate both sides of the first support area 212, and the guide member 271 may be arranged to at least partially surround the inner wall of the through hole 213. For example, when viewed from the front or rear of the first support area 212 along the Z-axis direction, the guide member 271 may have a closed curve shape surrounding the entire inner wall of the through hole 213. In one embodiment, the guide member 271 provides a wiring path (e.g., wiring hole 271a) for the flexible printed circuit board 266 and includes a synthetic resin material to form a wiring path for the flexible printed circuit board 266 and the flexible printed circuit board 266. Damage to the flexible printed circuit board 266 can be suppressed or alleviated even by contact or friction. When the through hole 213 is formed in the metal portion of the first support area 212 and the guide member 271 includes a synthetic resin material, the guide member 271 is molded through an insert molding process. It can be coupled to the first housing 210 at the same time.
