摘要： A motor (40) includes a stator (41) including a coil holding portion (42) and a first portion (43), and a rotor (46). The rotor includes a magnet holding portion (46a) that holds a magnet (46b). The magnet holding portion (46a) is located in an annular first space (S11) located radially outside the coil holding portion (42). The first portion (43) extending radially outward from the coil holding portion (42) has a first surface (43a) that is in contact with the first space (S11) and a second surface (43b) that is not in contact with the first surface (43a). A concave portion (43c) and a through hole (43d) are formed in the first portion (43).
