To provide a drum advance/retreat device capable of reducing influence of vibration of a device on a measured value even in a case where a test is conducted on a tire having a larger size than tires of ordinary passenger cars, and a tire testing machine comprising the drum advance/retreat device.SOLUTION: A drum advance/retreat device 400 comprises a rotary drum 4 that comes into contact with a tire, a drum housing 40 that rotatably supports the rotary drum 4, a base frame 100, a pair of ball screws 153, a pair of ball screw nuts 155, and a pair of linear guides 161. The base frame 100 supports the drum housing 40 so as to be able to move forward and backward. The base frame 100 has a plurality of vertical plates 115 including a pair of first vertical plates arranged directly under the pair of ball screws 153 and a pair of second vertical plates arranged directly under the pair of linear guides 161.SELECTED DRAWING: Figure 6

    【課題】普通乗用車のタイヤよりも大きなサイズのタイヤに対して試験を行う場合であっても、計測値に対する装置の振動の影響を低減することが可能なドラム進退装置およびこれを備えたタイヤ試験機を提供する。【解決手段】ドラム進退装置400は、タイヤに当接する回転ドラム4と、回転ドラム4を回転可能に支持するドラムハウジング40と、ベースフレーム100と、一対のボールねじ153と、一対のボールねじナット155と、一対のリニアガイド161とを備える。ベースフレーム100は、ドラムハウジング40を進退可能に支持する。ベースフレーム100は、一対のボールねじ153の直下に配置される一対の第1縦板と一対のリニアガイド161の直下に配置される一対の第2縦板とを含む複数の縦板115を有する。【選択図】図6
