1. A robot comprising:
a first member and
a second member that rotates relative to the first member, wherein
the first member includes
a housing including a first wall and a second wall disposed to face each other separated by a distance, a first protrusion protruding from the first wall toward the second wall, and a second protrusion protruding from the second wall toward the first wall,
a drive section including a motor body that generates a drive force rotating about a drive axis, a drive pulley that is connected to the motor body, and a flange that protrudes from the motor body in a direction intersecting the drive axis,
a joint section that has a driven pulley and that transmits the driving force to the second member, and
a belt wound around the drive pulley and the driven pulley, and
the first protrusion and the second protrusion include
support sections that support both end portions of the flange in the direction in which the flange protrudes, a separation distance between the support sections being shorter than a length of the flange in the direction in which the flange protrudes and
missing sections configured such that a separation distance between the missing sections is longer than the length of the flange in the direction in which the flange protrudes, both end portions of the flange passing through the missing sections.
