BOTTLE CLAMPER AND WHEEL DEVICE

To provide a bottle clamper and a wheel device capable of holding bottles different in a diameter, reduced in the number of grip arms and simplified in a configuration.SOLUTION: The bottle clamper 13 includes: one-side grip arms 15a, 15b disposed vertically at an interval; a the-other-side grip arm 17; and arm holding parts 19a, 19b for closing and opening the one-side grip arms and the the-other-side grip arm by moving them to a holding position and a non-holding position of a bottle body part. The one-side arms 15a, 15b and the-other-side grip arm 17 have holding surfaces 23, 27 opposed to each other. The respective holding surfaces 23, 27 have base end side surfaces 23a, 27a and tip side surfaces 23b, 27b disposed at intervals in an extending direction of the grip arms. The base end side surfaces 23a, 27a and the tip side surfaces 23b, 27b are formed linearly...
