Document Type and Number:
Japanese Patent JP2020045935
Kind Code:
A
Abstract:
To provide a tension adjustment device which has durability so that rotation moment is not generated at a support part even when receiving reaction force and is small in the number of part items, low in a cost, and easy in assembling to a power transmission device by an integrated simple constitution, and a grinder having the tension adjustment device.SOLUTION: A tension adjustment device 50 comprises a fixing member 51, an energization pulley 55, a slide member 56 and an elastic member 57. A center position of an energization reaction force which the energization pulley receives from a power transmission belt 42 is defined as a first center position D1, a center position of an energization force by which the elastic member energizes the slide member 56 is defined as a second center position D2, a position in which a guide member 53 of the fixing member 51 guides the slide member is defined as a guide position G, and a first distance L1 between the first center position and the second position is shorter than a second distance L2 between the first center position D1 and the guide position G.SELECTED DRAWING: Figure 4
