A printer includes a guide shaft, a rail member, print head units, a carriage and a first pressing portion. The first pressing portion includes a first contact member, a first support shaft, a first arm member and a first urging member. The first contact member comes into contact with a first end portion. The first support shaft is disposed between a position facing one of the two support portions in a rail-side end portion and a position facing the other support portion. The first support shaft stands in a fourth direction opposite to a third direction in which an ejection portion ejects liquid. The first arm member swings around the first support shaft, and supports the first contact member on a swinging end side. The first urging member urges the first arm member in a direction in which the first contact member comes into contact with the first end portion. |

1. A printer configured to perform printing by ejecting liquid onto a print medium that is fed in a first direction, the printer comprising:
a guide shaft being a shaft member having a center axis extending along a second direction, the second direction being a direction orthogonal to the first direction; a rail member disposed facing the guide shaft, the rail member being a rod-shaped member extending in the second direction; a plurality of print head units, each of the plurality of print head units having an ejection portion configured to eject the liquid toward the print medium; a carriage configured to arrange the plurality of print head units in the first direction and also configured to cause the plurality of print head units to reciprocate in the second direction, the carriage including two support portions, each of the two support portions being provided on a shaft-side end portion, the shaft-side end portion being one end portion of the carriage in the first direction, such that the carriage is slidably supported along the guide shaft by the guide shaft being inserted through each of the two support portions; and a first pressing portion provided on a rail-side end portion, the rail-side end portion being on an opposite side to the shaft-side end portion of the carriage in the first direction, such that the first pressing portion presses a first end portion of the rail member, the first end portion facing the guide shaft; wherein the first pressing portion includes
a first contact member provided so as to come into contact with the first end portion,a first support shaft disposed between a position of the rail-side end portion facing one of the two support portions and a position of the rail-side end portion facing the other of the two support portions, the first support shaft standing in a fourth direction opposite to a third direction in which the ejection portion ejects the liquid,a first arm member supported so as to swing around the first support shaft, the first arm member being provided so as to support the first contact member on a swinging end side opposite to a first support shaft side thereof, anda first urging member provided so as to urge the first arm member in a direction in which the first contact member comes into contact with the first end portion. |
